Peercoin12.2 Security Monitoring and EncryptionWhile encryption can bring many benefits to security and privacy protection, it can "add [a] little bit of chaos" to incident response and forensics. Even law enforcement agencies have been confused by the double-edged sword of encryption. In performing information and communication protection functions . . encryption benefits governments, the military, corporations, and even individuals. But conversely, threat makers can also use encryption as a means of evading detection and obfuscation. Historically, many governments have even tried to regulate the use and export of encryption technologies. A good example of this is the Wassenaar Arrangement, a multinational agreement to regulate the export of a range of technologies such as encryption.Other examples include incidents related to law enforcement agencies, such as the Federal Bureau of Investigation (FBI) attempting to force vendors to put certain backdoors in their own software and devices for investigative purposes. Another example is the existence of a so-called National Security Agency (NSA) backdoor in the Dual Elliptic Curve Deterministic Random Bit Generator (Dual_EC_DRBG), where any algorithm seeded by this pseudo-random number generator can be plaintext Extraction.The idea of "encrypting everything" is ingrained in the minds of many people. However, the serious consequences of "encrypting everything" not only confuse law enforcement agencies, but also affect professionals who respond to security incidents. One thing to keep in mind about the "encrypt everything" philosophy is that deploying end-to-end encryption is difficult and can put unencrypted data at risk of attack.Many security products (including next-generation IPS and next-generation firewalls) can intercept, decrypt, inspect, re-encrypt and even ignore encrypted traffic loads. Some believe this not only presents a man-in-the-middle (MITM) problem, but also460 Operational Difficulties Facing Chapter 12 Security Monitoringcan involve many privacy breach disputes. However, it is still possible to use metadata from network traffic and other security event sources to investigate and resolve security issues. A wealth of useful information can be obtained through NetFlow, firewall logs, Web proxy logs, user authentication information, and even passive DNS (pDNS) data. In some cases, the combination of the above information may make the encrypted content in malware netloads and other traffic irrelevant. Of course, as long as traffic patterns can be detected, information can be recovered from security incidents. In practice, encrypted data does need to be handled, but only if it is in transit or "at rest" on the endpoint (server). If a Web proxy is deployed, it needs to be evaluated for feasibility within the MITM secure HTTP connection environment.Tip: From a security monitoring perspective, it is important to know that it is possible to monitor certain encrypted communications at a technical level. However, from a policy perspective, this is a very specific task, and the degree of specificity depends on the different countries/regions and local laws related to privacy protection.
