"Penetration test" finds weak Network Points

Security devices play an important role in implementing network security, but relying solely on security devices is far from enough. The firewall can effectively resist hacker intrusion, but some attackers can bypass the firewall. IDS can detect illegal intrusions, but the false positives and false negatives of IDS make the network administrators exhausted. Security scanning tools can list a long string of "software vulnerabilities", but it takes several days for experienced professionals to figure out which vulnerabilities will cause actual harm to the network.
In the network environment, security devices are in the unknown, and hackers are in the dark and constantly looking for opportunities to bypass and attack security devices. In work and life, client software such as IE, Outlook, mIRC, and MSN Messenger has been indispensable. vulnerabilities of these software are being discovered one by one and exploited by hackers. Hackers are always scanning the weakest part of the network to obtain key information, which provides a breakthrough for further attacking the core system of the network. Discover and effectively prevent hacker attacks in a timely manner. Users not only need to use the corresponding security devices, but also need to perform "penetration testing" as appropriate to understand the network security situation.

Penetration Testing is commonly known as security assessment. Penetration Testing can check and audit the security of a network system from the perspective of an attacker. Because network security is a dynamic process, "penetration testing" also needs to be carried out periodically, and every six months is a good choice. An important part of penetration testing is regular assessment of open source software. Most network systems are using open source software. Without necessary security assessment, open source code will become an open door ". During the penetration test, I used vulnerabilities in the development source code, involving a wide range of software applications such as Sendmail and Squid, and many CGI applets. During the test, I found that as long as there is a small vulnerability, high-level attackers can gain a foothold in the target network, so as to display all the attack tactics, from attacking vswitches to implementing network eavesdropping. Hackers are very good at "virus removal", and it is very difficult to evict hackers from the system.

Any device may have security vulnerabilities, including the security product itself. Although many users use expensive high-end security devices, they have never performed professional security tests and evaluations on network systems. Penetration Testing proves that a vulnerable CGI program can destroy millions of security devices.
