Which Command Will Move the Show Access-Lists Command to Privilege Level 14?

Introduction

In the realm of network administration, securing and managing access to network devices is paramount. Cisco IOS, the operating system powering Cisco routers and switches, offers robust mechanisms to control user access through privilege levels. These levels allow administrators to assign specific commands to different user roles, ensuring that only authorized personnel can execute sensitive operations. One common task is configuring the show access-lists command, which displays access control lists (ACLs), to a specific privilege level, such as level 14.

The Role of Privilege Levels in Cisco IOS

Cisco IOS employs a privilege level system to manage access to commands, ranging from 0 to 15. Each level grants access to a specific set of commands, enabling granular control over what users can do on a device. By default, Cisco devices operate with three primary privilege levels:

Level 0: Offers minimal access, limited to basic commands like logout, enable, disable, help, and exit. This level is typically used for highly restricted access.
Level 1: The default user EXEC mode, providing read-only access to commands such as show and ping. Users at this level can view device status but cannot modify configurations.
Level 15: The privileged EXEC mode, granting full access to all commands, including configuration changes and sensitive operations. This is often reserved for senior administrators.

Levels 2 through 14 are customizable, allowing administrators to tailor access for specific roles, such as junior engineers or helpdesk staff. For example, a helpdesk team might need to view ACLs using show access-lists but should not have access to configuration commands. Assigning this command to a higher privilege level, like 14, ensures that only users with appropriate clearance can execute it. This flexibility is crucial in large organizations where role-based access control (RBAC) enhances security and operational efficiency.

Understanding privilege levels is essential for network security and is a key topic in Cisco certification exams. DumpsQueen offers practice questions and study materials that cover privilege level configurations, helping candidates prepare effectively for real-world and exam scenarios.

The Importance of the Show Access-Lists Command

The show access-lists command is a vital tool in a network administrator’s arsenal. It displays the details of all access control lists configured on a Cisco device, including standard and extended ACLs. ACLs are used to filter traffic, control access, and enforce security policies, making the ability to view them critical for troubleshooting and monitoring.

When executed, show access-lists provides information such as:

ACL names or numbers.
Permit or deny statements.
Source and destination IP addresses.
Protocols and ports.
Hit counts, indicating how often an ACL rule has been matched.

For instance, an administrator troubleshooting a connectivity issue might use show access-lists to verify whether an ACL is blocking specific traffic. By default, this command is available at privilege level 1, but in high-security environments, organizations may restrict its use to higher privilege levels to prevent unauthorized access to sensitive ACL details.

Moving the show access-lists command to privilege level 14 ensures that only users with elevated privileges can view ACL configurations, reducing the risk of information leakage or misuse. This is particularly relevant in environments with strict compliance requirements, such as financial institutions or government agencies. DumpsQueen study resources emphasize the practical applications of such commands, preparing candidates for both certification exams and real-world challenges.

Configuring the Show Access-Lists Command for Privilege Level 14

To move the show access-lists command to privilege level 14, the correct command is executed in global configuration mode. The precise syntax is:

router(config)# privilege exec level 14 show access-lists

This command modifies the privilege level of the show access-lists command, making it accessible only to users with privilege level 14 or higher (including level 15). Let’s break down the components of this command:

router(config)#: Indicates global configuration mode, where system-wide changes are made.
privilege exec: Specifies that the command affects EXEC mode commands, which include show commands.
level 14: Designates the target privilege level (14 in this case).
show access-lists: The specific command being reassigned.

Step-by-Step Configuration Process

Access Privileged EXEC Mode: Enter privileged EXEC mode using the enable command. You’ll need level 15 credentials unless a lower privilege level has been configured to access configuration mode.
```
Router> enable
Router#
```
Enter Global Configuration Mode: Use the configure terminal command to access global configuration mode.
```
Router# configure terminal
Router(config)#
```
Assign the Command to Privilege Level 14: Execute the command to move show access-lists to privilege level 14.
```
Router(config)# privilege exec level 14 show access-lists
```
Verify the Configuration: Use the show running-config | include privilege command to confirm that the privilege level has been updated.
```
Router(config)# do show running-config | include privilege
privilege exec level 14 show access-lists
```
Test the Configuration: Log in as a user with privilege level 14 and verify that the show access-lists command is accessible. Users with lower privilege levels (e.g., level 1) should no longer be able to execute it.

Assigning Users to Privilege Level 14

To ensure that specific users can access level 14 commands, you must assign them to this privilege level. This is done using the username command:

Router(config)# username admin privilege 14 secret password123

This command creates a user named admin with privilege level 14 and a password of password123. When this user logs in and enters enable 14, they can execute the show access-lists command, provided the earlier configuration is in place.

Verifying Privilege Levels

To confirm a user’s current privilege level, use the show privilege command:

Router> show privilege
Current privilege level is 1
Router> enable 14
Password: password123
Router# show privilege
Current privilege level is 14

This verification ensures that the user has the correct access and that the show access-lists command is available at level 14. DumpsQueen practice exams include scenarios like this, helping candidates master privilege level configurations and verifications.

Common Mistakes and How to Avoid Them

Configuring privilege levels can be tricky, and mistakes can lead to security vulnerabilities or access issues. Here are some common pitfalls and how to avoid them:

Incorrect Syntax

One frequent error is using incorrect syntax, such as:

router(config)# privilege level 14 command show access-lists

This command is invalid because it includes the unnecessary keyword command and omits the exec keyword. Always use privilege exec level for EXEC mode commands like show access-lists.

Misunderstanding Privilege Level Hierarchy

Commands assigned to a specific privilege level are accessible at that level and all higher levels. For example, moving show access-lists to level 14 makes it available to level 14 and level 15 users but not to those at level 13 or below. Ensure that all intended users have the appropriate privilege level.

Overlooking Default Privilege Levels

By default, show access-lists is available at level 1. After moving it to level 14, users at lower levels will lose access unless explicitly granted. Test the configuration thoroughly to avoid disrupting legitimate users.

Failing to Secure Passwords

When assigning users to privilege level 14, use the secret keyword instead of password to ensure that passwords are encrypted using a strong hashing algorithm (e.g., MD5). For example:

Router(config)# username admin privilege 14 secret password123

This enhances security compared to the plaintext password option. DumpsQueen study materials cover these best practices, ensuring you’re prepared for both exams and real-world configurations.

Practical Applications of Privilege Level Customization

Customizing privilege levels is a cornerstone of network security and operational efficiency. Here are some practical scenarios where moving commands like show access-lists to a higher privilege level is beneficial:

Helpdesk Support

In a large organization, helpdesk staff may need to view ACLs to troubleshoot connectivity issues but should not modify configurations. Assigning show access-lists to a custom privilege level (e.g., 14) allows them to perform their duties without risking unauthorized changes.

Compliance and Auditing

Organizations subject to regulatory standards, such as PCI DSS or HIPAA, must restrict access to sensitive information. Moving show access-lists to a higher privilege level ensures that only authorized personnel can view ACL details, aiding compliance efforts.

Junior Administrator Roles

Junior network engineers might need access to specific show commands for monitoring but should be restricted from configuration commands. Custom privilege levels provide a balance between access and security.

Third-Party Vendors

When external vendors require limited access to a network device, custom privilege levels ensure they can perform necessary tasks (e.g., viewing ACLs) without compromising the device’s security.

DumpsQueen certification resources include case studies and practice questions that simulate these scenarios, helping you apply theoretical knowledge to practical situations.

Best Practices for Managing Privilege Levels

To maximize security and efficiency when configuring privilege levels, consider the following best practices:

Use Role-Based Access Control (RBAC): Assign commands to privilege levels based on user roles to enforce the principle of least privilege.
Document Configurations: Maintain detailed records of privilege level assignments to simplify troubleshooting and auditing.
Test Changes in a Lab Environment: Before applying privilege level changes in a production environment, test them in a lab to avoid unintended access issues.
Leverage AAA: For advanced access control, integrate Authentication, Authorization, and Accounting (AAA) with TACACS+ or RADIUS to centralize user management.
Regularly Review Access Policies: Periodically audit privilege level assignments to ensure they align with organizational needs and compliance requirements.

DumpsQueen study guides include these best practices, helping you develop a holistic understanding of network security and access control.
