Why Do You Need One? Aside from protecting organization assets, a security policy serves other purposes, such as the following: Making employees aware of their security-practice obligations Identifying specic security solutions required to meet the goals of the security policy Acting as a baseline for ongoing security monitoring Components of the Security Policy What are the components found in the network security policy?
This section covers these details. Following are typical elements of this section: Identication of the issue addressed by the policy Discussion of the organizations view of the issue Examination of the relevance of the policy to the work environment Explanation of how employees must comply with the policy Enumeration of appropriate activities, actions, and processes Explanation of the consequences of noncompliance Technical Policies Technical policies provide a more detailed treatment of an organizations security policy, rather than the governing policy.
Elements of this section include the following: E-mail Wireless networks Remote access End-User Policies End-user policies address security issues and procedures relevant to end users. Senior management typically oversees the development of a security policy. Senior security or IT personnel are usually directly involved with the creation of the security policy.
Also, analysis must be performed of the probability that a threat will occur and the severity of that threat. This is risk analysis. When performing risk analysis, you can use one of two approaches: Quantitative analysis: Mathematically models the probability and severity of a risk. The ALE produces a monetary value that you can use to help justify the expense of security solutions. Qualitative analysis: Uses a scenario model, where scenarios of risk occurrence are identied. Collaborative: Collaboration occurs among the service and devices throughout the network.
Adaptive: The network can intelligently evolve and adapt the threats. Cisco Security Manager: Powerful but easy-to-use solution that enables you to centrally provision all aspects of device congurations and security policies for the Cisco family of security products MARS Cisco Security Monitoring, Analysis, and Response System : Provides security monitoring for network security devices and host applications made by Cisco and other providers Pearson Education, Inc.
This section details exactly how you must do this. Router Security Principles Following are three areas of router security: Physical security Operating system Router hardening Cisco Integrated Services Router Family Cisco Integrated Services Routers feature comprehensive security services, embedding data, security, voice, and wireless in the platform portfolio for fast, scalable delivery of mission-critical business applications.
Models include the Series, Series, Series, and Series. You must password-protect your router. These commands can be used: Console password line console 0 login password cisco Virtual terminal password line vty 0 4 login password cisco Enable password Secret password enable secret cisco All these passwords are in clear text in the configuration files with the exception of the enable secret command. To encrypt the passwords that are clear text, use the command service password-encryption.
To configure idle timeouts for router lines, use the command exec-timeout minutes [seconds]. You can also configure minimum password lengths with the security passwords min-length length command. To disable the ability to access ROMMON to disable password recovery on your router, use no service password-recovery. There are 16 privilege levels, 0 through Level 0 is reserved for user-level access privileges, levels 1 through 14 are levels you can customize, and level 15 is reserved for privileged mode commands.
To assign privileges to levels 2 through 14, use the privilege command from the global configuration mode. Remember that privilege levels cascade.
If a user has level 13 access, that user also gains access to the commands in levels 1 through Using this approach, different administrators have different views of the CLI.
These views contain the specific commands available for different administrators. Enable AAA. STEP 2. Use the enable view command to enable the feature. STEP 3. Use the congure terminal command to enter global conguration mode.
STEP 4. Use the parser view view-name command to create a new view. STEP 5. Use the secret command to assign a password to the view. STEP 6.
STEP 7. Verify using the enable view command. The secure boot-image command protects the IOS image, and the command secure boot-config protects the running configuration.

These protected files do not appear in a dir listing of flash. To see these protected files, use the show secure bootset command. This command is mandatory; all other commands here are optional. The devices that match a permit statement in the ACL are exempt from the quiet period. Banner Messages Banner messages are important. With these messages, you can ensure that unauthorized personnel are informed that they will be prosecuted for illegal access. These appear on the top button bar.
When you click either Configure or Monitor, many options appear down the button bar on the left side of the screen. Many of these options lead to a wizard that aids in the configuration. Building Blocks for Ease of Management There are some new additions to the Cisco Configuration Professional that directly address the ease of management for larger environments. These features include Communities, Templates, and User Profiles.
Communities: Groups of devices that share common components Templates: Allows the simple replication of settings User proles: GUI views that provide role-based access control for different administrators Using AAA with the Local Database Authentication, authorization, and accounting AAA services are a powerful security addition to any organization.
This section details the use of these services with a local database on the router or switch. Authorization dictates what these users can do after they are authenticated.
Accounting tracks what users do. You can use AAA pronounced triple A to control administrative access to the device and access to the network through the device. The two modes are character mode when the user tries to connect to the router for admin , and packet mode 0 when the user tries to connect through the router for access to the network beyond.
You can make additional settings at the command line. For example, to specify the maximum number of unsuccessful authentication attempts before a user is locked out, use the aaa local authentication attempts max-fail command in global configuration mode. To display a list of all locked-out users, use the show aaa local user lockout command in privileged EXEC mode.
Use the clear aaa local user lockout command in privileged EXEC mode to unlock a locked-out user. You can use the show aaa sessions command to show the unique ID of a session. The aaa authentication login default local command denes the default method list for login authentication using the local database.
The username command adds a username and password to the local security database. New in ACS 5. Rule-based policies provide a more flexible approach that can match on a variety of access conditions found in current networks. This would include access, location, access type, time, date, and so forth.
Add router as AAA client. Add a Laptop to the Cisco Packet Tracer workspace. Physical Setup To make a network, we first need a source such as a network hub.
