Ethical issues security professionals

Physicians, attorneys and other professionals whose job duties affect others' lives usually receive, as part of their formal training, courses that address ethical issues common to their professions. IT security personnel often have access to confidential data and knowledge about individuals' and companies' networks and systems that give them a great deal of power. That power can be abused, either deliberately or inadvertently. But there are no standardized training requirements for hanging out your shingle as an IT security consultant or in-house security specialist. Associations and organizations for IT pros are beginning to address the ethical side of the job, but again, there is no requirement for IT security personnel to belong to those organizations. Why are ethical guidelines needed? The education and training of IT professionals, including security specialists, usually focuses on technical knowledge and skills. You learn how to perform tasks, but with little ...

Best Practices for DDoS

I found this  doc ument from Google that explains the best practices to this cases. GCP load balancing solution has DDoS mitigations built-in lowering the attack surface: configure ingress firewall rules (like iptables) network load balancing has port filtering. Any port that is not loadbalanced is dropped by GCP highly scaling frontend infrastructure HTTP/HTTPS loadbalancing can absorb and protect from IP spoofing and large SYN flood attacks. it has also fair-share allocation built-in  And Google Cloud Platform provides a number of features to defend against DDoS attacks. You can use these in conjunction with the above mentioned best practices and other measures tailored to your requirements to make your GCP deployment resilient to DDoS attacks.

Cryptography

Cryptography has been here since we are, we have to remember that to break a cryptography system was the objective of the first computers but also that cryptography and security are always related on iT or other for example: Every poker player should learn a bit about cryptography. Because, in a way, playing poker is actually a form of cryptography. Let me explain. Cryptography is the science of encoding information. Typically encryption is used to encode communications between two parties so that a third party is unable to understand it. For millennia, people have been trying to encrypt their communications—and the field of cryptography has become increasingly important over the years. All of the innovation in cryptography is designed to address one problem. There is an inherent tradeoff between ease-of-use of a cryptographic method and its security. Interestingly, if you are interested only in security—making sure that no one can possibly break your code—and not at all in ea...
