In the gated residential area where your grandparents reside, certain regulations govern the entry and exit procedures. To gain access to the community, the security personnel will only raise the gate once your presence has been verified against an authorized visitor list. Similarly, when it comes to network traffic traversing an interface set up with an access control list (ACL), there are provisions for permitting or denying traffic. How can you go about configuring these ACLs? Furthermore, what steps should you take if they are not functioning as intended or need adjustments for other reasons? Begin exploring this module to acquire a deeper understanding.
Introduction to Access Control Lists
Routers play a critical role in making routing decisions based on information contained in the packet header. When traffic enters a router interface, the routing decision is primarily guided by the data within the routing table. Specifically, the router conducts a comparison between the destination IP address and the routes stored in the routing table to identify the most suitable match. Subsequently, the packet is forwarded based on the determined best-match route. This same mechanism can be harnessed for the purpose of traffic filtration through the utilization of an access control list (ACL).
An ACL is essentially a series of IOS (Internetwork Operating System) commands designed to filter packets by examining details within the packet header. By default, a router does not have any ACLs in place. However, when an ACL is applied to a specific interface, the router assumes an additional responsibility: it evaluates all incoming network packets as they traverse the interface to ascertain whether a packet can be forwarded.
The structure of an ACL consists of a sequential list of statements, known as access control entries (ACEs). It is worth noting that ACEs are often referred to as ACL statements.
When network traffic passes through an interface configured with an ACL, the router assesses the information contained within each packet against the ACEs, one after the other in sequence. This process, known as packet filtering, aims to determine if the packet aligns with any of the ACEs.
Routers frequently employ ACLs for various tasks, relying on them to identify specific types of traffic. The table below provides some examples of these tasks:
Traffic Permitting – Permitting certain traffic types while denying others.
Security Measures – Enhancing network security by controlling access.
Quality of Service (QoS) – Prioritizing traffic based on service requirements.
Traffic Accounting – Keeping track of data usage for billing or monitoring.
Network Address Translation (NAT) – Managing the translation of private IP addresses to a public one for internet access.
By skillfully configuring ACLs, network administrators can effectively manage and secure their network traffic to meet specific operational requirements.
Packet Filtering
Packet filtering serves as a mechanism for managing network access by scrutinizing incoming and/or outgoing packets and making decisions about whether to allow or discard them according to predefined criteria. This process of packet filtering can be implemented at either Layer 3 or Layer 4 of the network protocol stack, as illustrated in the diagram.
Numbered and Named ACLs
Named ACLs
ACLs are categorized into two main types: standard and extended. Standard ACLs are numbered from 1 to 99 or from 1300 to 1999, while extended ACLs are numbered from 100 to 199 or from 2000 to 2699. This categorization of ACLs are following:-
1-99 IP standard access list
100-199 IP extended access list
1100-1199 Extended 48-bit MAC address access list
1300-1999 IP standard access list (expanded range)
200-299 Protocol type-code access list
2000-2699 IP extended access list (expanded range)
700-799 48-bit MAC address access list
rate-limit Simple rate-limit specific access list
template Enable IP template acls
Named ACLs
Using named ACLs is the recommended approach when configuring Access Control Lists (ACLs). With named ACLs, you can provide descriptive names that convey the purpose of the ACL, which makes it easier to understand and manage. For instance, naming an extended ACL “FTP-FILTER” is much more informative than using a numeric identifier like ACL 100.
To create a named ACL, you can use the “ip access-list” global configuration command. This allows you to define ACLs with meaningful names, enhancing clarity and organization in your network configuration, as shown in the following example.
permit tcp 192.168.10.0 0.0.0.255 any eq ftp
permit tcp 192.168.10.0 0.0.0.255 any eq ftp-data
Here is a summary of the rules to adhere to when working with named ACLs:
Assign a Descriptive Name: Choose a name that clearly identifies the purpose of the ACL, making it easy to understand its role in network security or traffic management.
Alphanumeric Characters: Use only alphanumeric characters (letters and numbers) in the ACL name. Avoid using spaces or punctuation marks.
Consider Uppercase: While not mandatory, it’s often recommended to write the name in CAPITAL LETTERS for consistency and visibility in network configurations.
Dynamic Editing: Keep in mind that you can add or remove entries within the ACL as needed, allowing for flexibility in managing access control based on changing network requirements.
ACL Operation
Access Control Lists (ACLs) serve as a set of rules that provide additional control over packets as they interact with a router. ACLs can be configured to apply to inbound and outbound traffic, as depicted in the figure.
The figure illustrates inbound and outbound traffic on a router. In the center is a router, and on the left, there’s an orange arrow pointing toward the router, accompanied by the label “Inbound ACL.” On the right, another orange arrow starts at the router and points away, accompanied by the label “Outbound ACL.”
Important Notes: ACLs do not impact packets originating from the router itself.
Inbound ACLs are responsible for filtering packets before they are routed to the outbound interface. This approach is efficient because it prevents unnecessary routing lookups if a packet is to be discarded. If the ACL permits the packet, it proceeds to the routing process. Inbound ACLs are ideal when you need to examine packets originating exclusively from the network attached to an inbound interface.
Outbound ACLs, on the other hand, filter packets after they have been routed, irrespective of the inbound interface. Incoming packets are first routed to the outbound interface and then subjected to the outbound ACL. Outbound ACLs are suitable when the same filtering criteria must be applied to packets arriving from multiple inbound interfaces before exiting via the same outbound interface.
When an ACL is applied to an interface, it follows a specific sequence of operations. For instance, here are the steps involved when traffic enters a router interface with an inbound standard IPv4 ACL configured:
The router extracts the source IPv4 address from the packet header.
The router commences at the top of the ACL, comparing the source IPv4 address to each Access Control Entry (ACE) in a sequential manner.
When a match is identified, the router executes the specified action (permit or deny), and the remaining ACEs in the ACL are not examined.
If the source IPv4 address doesn’t match any ACE in the ACL, the packet is discarded because there is an implicit deny ACE that applies to all ACLs by default.
The final ACE statement in an ACL is always an implicit deny, blocking all traffic. This statement is automatically included at the end of every ACL, even though it isn’t displayed in the configuration.
Note: An ACL must contain at least one permit statement; otherwise, all traffic will be denied due to the implicit deny ACE statement.
The security of our online actions and data is critical in this day and age of digital technology. Given the increasing sophistication of cyber attacks, it is imperative to implement robust security measures. Firewalls and intrusion detection systems (IDS) are two crucial components of this security framework. In this comprehensive book, we will delve into the world of firewalls and intrusion detection systems (IDS), discovering its significance, workings, and potential ways to bolster your digital defenses against incursions.
First Off
In our globally interconnected society, where information travels at the speed of light, there is always a risk of cyberattacks. It is essential to stay up to date with cybersecurity advances since malicious actors and hackers are constantly coming up with new ways to circumvent digital defenses.
Knowing How to Use Firewalls
Define a firewall.
A firewall is a type of software or hardware for network security that separates an untrusted network from a trusted network. It functions as a kind of digital gatekeeper, regulating network traffic flow according to preset security guidelines.
Various Firewall Types
There are various kinds of firewalls, each with a unique set of characteristics and capabilities, such as stateful inspection firewalls, proxy firewalls, packet-filtering firewalls, and next-generation firewalls.
Firewall Operation
Firewalls distinguish between traffic that is allowed and prohibited using a variety of rules, including stateful inspection and access control lists. They keep an eye on all incoming and outgoing data packets and determine if they satisfy the predetermined standards.
Intrusion Detection Systems’ Function
IDS: What is it?
A security technology called an intrusion detection system (IDS) actively watches network or system activity for unusual activity or policy violations. Similar to a digital alarm system, it notifies you when it sees any dangers.
Classes of IDS
Network-based IDS (NIDS) and host-based IDS (HIDS) are the two primary types of intrusion detection systems (IDS). Whereas HIDS keeps an eye on actions on specific devices, NIDS analyzes network traffic.
How IDS Operates
IDS detects possible intrusions using a variety of techniques, including anomaly-based detection and signature-based detection. Whereas anomaly-based intrusion detection systems (IDS) search for departures from predetermined baselines, signature-based IDS analyzes network activity to a library of recognized attack patterns.
Comparing Intrusion Detection Systems with Firewalls
IDS and firewalls are security measures, however they play different roles. As a barrier, firewalls allow or prohibit communication according to pre-established rules, while intrusion detection systems (IDS) continually watch for unusual activity.
Reasons Your Company Needs Both
To offer a solid security posture, firewalls and intrusion detection systems (IDS) must be installed. Firewalls constitute the first line of defence, and intrusion detection systems (IDS) serve as an alert system by spotting potential security breaches.
Configuring a Firewall
Configuring a firewall requires careful planning and paying attention to best practises. Make sure the rules on your firewall comply with your company’s security policy, and make sure you update them often to stay ahead of emerging dangers.
Setting Up a System for Intrusion Detection
It’s critical to adjust the sensitivity of an intrusion detection system (IDS) during configuration in order to prevent false positives and yet identify possible threats. To keep up with new threats, check and update your IDS rules on a regular basis.
Working together: IDS and firewall
IDS and firewalls work together to provide a powerful security team. While intrusion detection systems (IDS) offer real-time threat monitoring that enables prompt action, firewalls provide a robust perimeter defense.
Practical Utilizations
IDS and firewalls are not just for use in offices. They are similarly important for home networks, protecting your private information from online attacks.
Common Difficulties
Negatives and False Positives
The incidence of false alarms (false positives) or the inability to identify actual threats (false negatives) is a problem when utilizing IDS. Your IDS can be adjusted to help reduce these problems.
Instability Concerns
IDS and firewall management becomes more complex as your network expands. These difficulties can be addressed by putting automation and scalable solutions into practice.
Changing Environment of Threats
Cyberthreats are ever-changing. To keep ahead of nefarious actors, keep up with the latest threats and upgrade your security procedures accordingly.
The Role of People in Cybersecurity
Technology is not the only factor that affects cybersecurity. A comprehensive security strategy must include training staff members on cybersecurity best practices and increasing public awareness of social engineering techniques.

Why is training employees so important in cybersecurity?
Because human error is frequently a weak link in cybersecurity, employee education is crucial. Employees with more education are better able to identify and thwart online risks.
Zero trust represents a comprehensive strategy for securing access across various domains such as networks, applications, and environments. This method ensures the protection of access rights for users, end-user devices, APIs, IoT devices, microservices, containers, and more. It safeguards an organization’s workforce, workloads, and workplace.
The fundamental principle underlying the zero-trust approach is “never trust, always verify.” It implies that every time someone or something requests access to assets, they should be treated as untrusted until their identity is verified. The zero-trust security framework is designed to prevent unauthorized access, contain breaches, and minimize the potential for attackers to move laterally within a network.
Traditionally, the network perimeter, also known as the edge, served as the dividing line between trusted and untrusted areas. However, in the context of the zero-trust approach, any point where access control decisions are made should be regarded as a potential perimeter.
This means that even if a user or entity has previously gained access through one access control point, they are not automatically trusted to access other areas or resources unless they authenticate themselves. In certain situations, users may need to authenticate multiple times and use different methods to access different layers of the network. There are three pillars of zero trust security which are workforce, workloads, and workplace.
Zero Trust for the workforce
This aspect involves individuals, including employees, contractors, partners, and vendors, who utilize their personal or company-managed devices to access work-related applications. This facet of security guarantees that only authorized users and trusted devices can access applications, irrespective of their location
Zero Trust for the workload
This component addresses applications operating in cloud environments, data centers, and various virtualized settings, all of which communicate with each other. Its primary emphasis is on ensuring secure access when an API, microservice, or container needs to interact with a database within an application.
Zero Trust for the Workplace
This aspect prioritizes ensuring secure access for all types of devices, including those within the Internet of Things (IoT), that establish connections with enterprise networks. These devices encompass user endpoints, physical and virtual servers, printers, cameras, HVAC systems, kiosks, infusion pumps, industrial control systems, and various others.
Access Control Models
To safeguard its network resources, information systems, and information, an organization needs to establish effective access controls. To gain insight into potential vulnerabilities and threats, a security analyst should grasp the fundamentals of various access control models, enabling them to comprehend how attackers may attempt to circumvent these security measures.
Discretionary Access Control (DAC)
This model, known as the least restrictive, empowers data owners to manage access to their data. In the context of DAC (Discretionary Access Control), access permissions can be defined using ACLs (Access Control Lists) or alternative approaches to indicate which users or user groups are granted access to the information.
Mandatory Access Control(MAC)
This approach enforces the most stringent access control measures and is commonly employed in military or highly critical applications. It involves assigning security-level labels to information and granting access to users based on their security clearance level.
Role-Based Access Control(RBAC)
Access determinations are rooted in an individual’s functions and duties within the organization. Various roles are granted specific security privileges, and individuals are linked to the Role-Based Access Control (RBAC) profile corresponding to their role. These roles can encompass diverse positions, job categories, or groups of job categories. This system is also referred to as a form of non-discretionary access control.
Attribute-based access control(ABAC)
ABAC permits access based on attributes related to the object (the resource being accessed), the subject (the user seeking access), and environmental factors pertaining to how the object should be accessed, such as the specific time of day.
Rule-Base Access Control(RBAC)
The network security team establishes sets of regulations or criteria linked to data or system access. These regulations can define allowed or prohibited IP addresses, particular protocols, and other related conditions. This approach is also recognized as Rule-Based Role-Based Access Control (RBAC).
Time-based Access Control (TAC)
Another access control model is the “principle of least privilege,” which advocates a restricted, necessity-based approach to bestowing user and process access privileges for particular information and tools. This principle asserts that users should only be provided with the minimal level of access essential for carrying out their job responsibilities.
A prevalent form of exploitation is known as “privilege escalation.” In this type of attack, vulnerabilities within servers or access control systems are manipulated to confer an unauthorized user or software process with higher privileges than they should rightfully possess. Once these elevated privileges are obtained, malicious actors can access sensitive data or gain control over a system.
Network Access Control (NAC) Systems
Network Access Control (NAC) systems play a crucial role in managing access to a network by enforcing an organization’s policies regarding individuals and devices seeking network access. These systems enable cybersecurity experts to oversee the users and devices connected to the network and exercise manual control over access when necessary.
NAC systems offer the following capabilities:
Swiftly implementing access policies tailored to various operational scenarios.
Identifying and profiling users and devices connected to the network to prevent potential harm from non-compliant systems infected with malicious software.
Facilitating secure access for network guests, often through registration portals.
Assessing device compliance with security policies based on user type, device type, and operating system before granting network access.
Addressing security incidents by either blocking, isolating, or rectifying non-compliant devices.
Given the expanded attack surface brought about by Bring Your Own Device (BYOD) and Internet of Things (IoT) networking, NAC system automation features become indispensable for maintaining precise control over network access by such devices. These NAC systems are configured to uphold organizational policies, with these policies determining whether network access is granted or denied based on various factors detected by the NAC system on devices seeking access. Without NAC systems, it would be unmanageable for cybersecurity personnel to evaluate the multitude of devices attempting to access the network.
NAC serves as a pivotal component within a zero-trust security framework, ensuring compliance with security policies for all devices and users endeavoring to access the network.

Physical access controls refer to tangible measures put in place to obstruct any direct physical interaction with systems. The primary objective is to hinder unauthorized individuals from obtaining physical entry to facilities, machinery, and other assets within an organization. To illustrate, physical access control governs who is permitted to enter or exit, specifies the locations at which entry or exit is allowed, and dictates the times at which entry or exit is granted.
Here are some examples of physical access controls:

Administrative Access Controls in Detail
Let’s delve deeper into the specifics of administrative access controls. The concept of administrative access controls revolves around three fundamental security services: authentication, authorization, and accounting, often referred to as AAA. These services form the core framework for managing access, effectively thwarting any unauthorized entry into a computer, network, database, or other data resources.
Authentication
The initial “A” in AAA stands for authentication, a process that validates the identity of each user to prevent unauthorized access. Users establish their identity using a username or ID, and they are also required to confirm their identity by providing one of the following:
Something they remember (like a password)
Something they possess (such as a token or card)
Something inherent to them (such as a fingerprint)
With the rise of two-factor authentication, which is now more commonly practiced, the system mandates the use of a combination of two of the aforementioned methods instead of relying on just one to confirm an individual’s identity.
Authorization
Authorization services are responsible for establishing which resources users are allowed to access and what actions they can perform. In certain systems, this is achieved through the utilization of an access control list (ACL). An ACL assesses whether a user possesses specific access privileges after their authentication. It’s important to note that simply logging onto the corporate network does not automatically grant permission for activities like using a high-speed color printer.
Authorization can also dictate when a user is granted access to a particular resource. For instance, employees may have access to a sales database during their work hours, but the system restricts access after regular working hours.
Accounting
Unrelated to financial accounting, within the realm of AAA (Authentication, Authorization, and Accounting), accounting focuses on monitoring user activities, which includes tracking their actions, the duration of resource access, and any alterations they make.
For instance, consider a bank that meticulously records every customer account. An audit of this system can unveil the timing and amounts of all transactions, as well as the employee or system responsible for carrying out these transactions. Cybersecurity accounting services operate in a similar fashion. The system logs each data transaction and generates audit reports. System administrators have the capability to establish computer policies to facilitate system auditing.
The AAA concept can be likened to using a credit card. Much like how a credit card specifies who can utilize it, sets spending limits for the user, and documents the items or services acquired, AAA systems encompass the identification of users, the control of their actions, and the recording of their activities.
What Is Identification?
Identification is the process that upholds the rules set forth by the authorization policy. Whenever there’s a request for access to a resource, the access controls step in to decide whether access should be granted or denied.
A distinct identifier plays a crucial role in ensuring the correct association between authorized activities and individuals. The most common means of identifying a user is through a username, which can take the form of an alphanumeric combination, a personal identification number (PIN), a smart card, or a biometric method such as fingerprint recognition, retina scanning, or voice recognition.
The presence of a unique identifier guarantees that the system can individually recognize each user, thus enabling authorized users to carry out appropriate actions on specific resources.
Federated Identity Management
Federated identity management involves multiple enterprises enabling their users to utilize the same identification credentials to access the networks of all enterprises within the group. However, this practice broadens the scope and raises the likelihood of a cascading effect in the event of an attack.
In a broader sense, federated identity links an individual’s electronic identity across distinct identity management systems, enabling them to access various websites using the same social login credentials.
The primary objective of federated identity management is to automatically share identity information across different domains. For users, this translates to a single sign-on experience on the web.
It is essential for organizations to carefully examine the information shared with their partners, even if they belong to the same corporate group. Sharing sensitive data like social security numbers, names, and addresses could potentially provide identity thieves with an opportunity to commit fraud. The most common method for safeguarding federated identity is to associate login capabilities with an authorized device.
Authentication Methods
As previously mentioned, users establish their identity through a username or ID. Additionally, users are required to confirm their identity by furnishing one of the following:
What you know
Passwords, passphrases, or PINs represent examples of information known to the user, with passwords being the most widely used method for authentication.
Terms like passphrase, passcode, passkey, and PIN are all collectively referred to as passwords. A password is essentially a sequence of characters used to confirm a user’s identity. However, if this character sequence is related to the user in an obvious way, such as using their name, birthdate, or address, it becomes easier for cybercriminals to guess.
Numerous sources recommend that a password should consist of at least eight characters. Users should strike a balance between creating a password that is long enough for security but not so long that it becomes difficult to remember. Additionally, it’s essential for passwords to incorporate a mix of uppercase and lowercase letters, numbers, and special characters.
To enhance security, users should employ different passwords for various systems. This precaution is crucial because if a cybercriminal manages to crack one password, they would gain access to all of the user’s accounts. Utilizing a password manager can assist in generating and managing strong passwords, eliminating the need to remember each one individually.
What You have
Smart cards and security key fobs serve as examples of physical items that users possess and can use for authentication purposes.
A smart card is a compact plastic card, roughly the size of a credit card, containing a small embedded chip. This chip functions as an intelligent data carrier, capable of processing, storing, and safeguarding data. Smart cards hold sensitive information like bank account numbers, personal identification, medical records, and digital signatures. They employ encryption to secure data while also providing a means for authentication.
On the other hand, a security key fob is a small device that can be easily attached to a keyring. Security key fobs are typically employed for two-factor authentication (2FA), which is notably more secure than relying solely on a username and password combination.
For instance, let’s consider a scenario where you wish to access your e-banking account, which utilizes two-factor authentication. First, you enter your username (the first identification step), followed by your password, serving as the initial authentication factor. Then, you require a second factor, as it’s 2FA. To complete this, you input a PIN or insert your smart card into the security key fob, which then displays a number. By demonstrating that you possess this device, which was assigned to you, this number serves as the second factor. You subsequently enter this number to log in to your e-banking account, as illustrated in this example.
What You are
Biometrics refers to distinctive physical traits like fingerprints, retinas, or voices that serve as unique identifiers for individuals. Biometric security involves comparing these physical characteristics to stored profiles in order to verify users’ identities. In this context, a profile is a data file containing recognized attributes of an individual. If a user’s characteristics align with the stored data, the system grants them access. A fingerprint reader is a widely used biometric device for this purpose.
There are two types of biometric identifiers:
Physiological characteristics — fingerprints, DNA, face, hands, the retina or ear features.
Behavioral characteristics —patterns of behavior such as gestures, voice, gait or typing rhythm.
Biometrics is gaining growing popularity in various fields, including public security systems, consumer electronics, and point-of-sale applications. To implement biometrics, you typically need a reader or scanning device, software that transforms scanned data into digital format, and a database containing biometric data for comparison.
Multi-Factor Authentication
As mentioned earlier, multi-factor authentication involves using at least two verification methods, such as a password and a physical item like a security key fob. It can be enhanced further by including a biometric factor, such as a fingerprint scan.
Multi-factor authentication significantly reduces the risk of online identity theft because merely knowing a password will not grant cybercriminals access to a user’s account.
For instance, consider an online banking website that requires both a password and a one-time PIN received on the user’s smartphone. In this scenario, the password serves as the first factor, while the temporary PIN serves as the second factor, confirming the user’s access to their registered phone.
Another straightforward example of multi-factor authentication is cash withdrawal from an ATM, where the user must possess the bank card and know the associated PIN before the ATM dispenses cash.
It’s important to note that two-factor authentication (2FA) is a specific form of multi-factor authentication that involves precisely two factors. However, these terms are often used interchangeably.
