This approach enforces secrecy as the primary security measure. It relies on hiding crucial security information from the stakeholders and users. STO, security through obscurity, or security by obscurity, is a well-known approach for securing a system or an application. Definition of security through obscurity (STO) Our vCISOs will ensure your optimal cybersecurity strategy and adequate posture. Our services such as comprehensive gap assessment, red-teaming, penetration testing, threat hunting and vulnerability assessment reveal a company’s vulnerabilities. LIFARS is an industry leader that develops proactive strategies and tactics against evolving cybersecurity threats. This belief has been around for decades, and there are arguments on both the sides of the spectrum: whether security through obscurity is good or not. The proponents of this belief consider that if the attackers are not aware of security measures employed in a target system, security is better. From the attackers’ perspective, they attempt to gather information about target systems for better planning and executing their attacks.īased on this common understanding of attacker psychology, “security through obscurity” is an existing belief in the information security industry. These measures include applying patches, disabling unnecessary services, and finetuning firewall rules, among others. Security teams implement various measures to achieve this objective and ensure a strong defense against incoming attacks.

Perhaps the best conclusion is that, as one user commented on Information Security Stack Exchange, "Security ONLY through obscurity is terrible." Referring to the previous example, changing to a non-standard port in addition to using strong SSH password and key protection is probably an excellent idea. While further digging can locate the administrator's numerical security identifier, at the very least the intruder has been slowed down. This simple measure will slow down any hacker trying to log in as an administrator. For example, many security professionals advocate hiding the administrator account. However, as TechNet Magazine points out, obscurity can be a useful tool when added to existing layers of high-quality encryption.

The Open Web Application Security Project gives a good example of Kerckhoff's principle at work: Linux source code is available through countless open doors, and yet when secured with proper keys it makes a robustly impenetrable operating system. Kerckhoff's principle, which directly contradicts "security through obscurity," still remains a best practice in today's information age.

This principle centers on the expectation that enemies will acquire access to the full architecture of a system, and so safety lies in an explicit cryptographic key rather than in the hope of keeping the system's structure secret. He stated that a system's security should lie wholly in its key, and that as long as the key remains unknown the system should remain secure. Interestingly enough, the principles of 21st century computer security are based on a nineteenth century axiom created by cryptographer Auguste Kerckhoff. IT Security Should Follows this Historic Principle While this would stop some attacks, a knowledgeable intruder would simply run a port scanner until he or she finds a server using a non-standard port and would then have access to the server. TechNet Magazine gives an example in which a vulnerable web server that could be attacked through Port 80 simply switches to Port 81. If the safety of an application relies on its source code remaining unknown, that provides little protection.
What can work well in a brief window of the physical world, however, is less safe in the never-sleeping online universe. Some computer security experts say this concept can be applied to protecting vital data, but, due to fundamental vulnerability, it should never be the sole Publish approach for computer security. This particular transaction was successful because it didn't raise the suspicion of thieves. It was put to test in the real world in 2008, when the American Numismatic Society transported a collection of rare coins worth hundreds of millions of dollars by using ordinary moving trucks and movers unaware of the precious cargo. For the uninitiated, the term is a security strategy that emphasizes secrecy over protections.
* Despite the term security by obscurity's pejorative origin, it has a place in computer security. In the never-sleeping online universe these same methods won't carry over too perfectly. * In the physical world, secrecy is an asset to security.
