Security posture assessment analysis and documentation

By assessing all aspects of the networked business environment, it is possible to determine the ability of the organization to detect, defend against, and respond to network attacks. These are the key activities Security posture assessment The first step in planning network security requires an evaluation of the network security posture of the organization. The security posture assessment provides a snapshot of the security state of the network by conducting a thorough assessment of the network...

Keep keys for encrypted information secure and available

Every system eventually reaches its end of life, and components within the system break down or simply wear out. The disposal phase of the system life cycle involves the state of information, hardware, and software no longer required or of use. Activities include moving, archiving, discarding or destroying information, and sanitizing the media. Disposal activities must meet all applicable regulations and directives. The disposal phase of the network life cycle involves the state of information,...

How Routers Enforce Perimeter Security Policy

Routers are used to secure the perimeter of networks. Three typical methods are as follows In scenario 1, the router protects the LAN. In scenario 2, the router provides defense in depth by screening traffic before a firewall. In scenario 3, the zone between R1 and R2 is called a DMZ. Servers that must be accessible from the Internet can be put here. A router provides a capability to help secure the perimeter of a protected network. It is a device where security action, based on the security...

The aaa authentication enable default command

After enabling AAA globally on the access server, you need to define the authentication method lists and apply them to lines and interfaces. These authentication method lists are security profiles that indicate the service, PPP, dotlx, or login and authentication method. Up to four authentication methods (local, group TACACS+, group RADIUS, line, or enable authentication) may be applied to a line or interface. A good security practice is to have either local or enable authentication as the...

HELLO Welcome to httpwwwwormcom Hacked By Chinese

Port redirectors can help bypass port filters, routers, and firewalls, and can evade intrusion detection. For example, assume that a firewall has ports 80 (HTTP) and 443 (HTTPS) open by default, but port 443 is unused. Assume that there is a database server on port 3389 (ms-wbt-server). A hacker can select port 443 as a listening port and remain undetected. The hacker can then set up a port redirector without disrupting operations. A port redirector takes traffic coming in on one port and...

Authentication commands can be applied to lines or interfaces

Note It is recommended that you always define a default list for AAA to provide last resort authentication on all lines and interfaces protected by AAA. As shown in the figure, authentication commands can be applied to router lines and interfaces.
