is a cisco certification worth it.for the purpose of hiding malicious code. Let's say an attacker uses SSL encryption from a web server to circumvent detection by a network intrusion detection system.The attack is launched from a Web server with SSL encryption. Since network intrusion detection systems detect threats based on signatures, as long as the traffic to be detected is encrypted, the threat is undetectable.the threat is undetectable. Another example is encoding a malicious file with a bunch of meaningless text in order to "fool" the antivirus software.Another example is encoding a malicious file with a bunch of meaningless text in order to "get past" the antivirus software. Anti-virus software also detects threats based on signatures, adding additional text to the malicious code to "qualify" it.The antivirus software will also detect the threat based on the signature, adding additional text to the malicious code to "qualify" it. In this way, the antivirus software will not detect the attack associated with the malicious code.Key encryption and tunneling concepts The following are important concepts related to key encryption and tunneling. (flA VPN can be used to hide or encode something to prevent an unrelated person from learning its contents. " Encrypted traffic may bypass detection by some threat prevention systems (for example. IPS).There are two types of optional-access VPNs-client-based remote access VPNs and clientless remote access VPNOsSite-to-site VPNs are available to interconnect two or more networks.SSH connects a host to an SSH server with public key encryption to authenticate the remote computer and allow it to authenticate users. File encryption technology prevents files from being accessed by unauthorized users. The next section describes how to bypass the detection of security defenses with the help of a resource depletion attack on an unauthorized14.3 Resource depletion 497
