Input validation is less about specific vulnerabilities
Security takes a layered approach to reduce the risk to our organization. Input validation is the perfect example of one of these layers. In most cases, input validation is 1 factor in a multi-pronged approach to protecting against common vulnerabilities. Take any course on secure development and they will, or should, mention input validation as a mitigating control for so many vulnerabilities. You might notice that it always comes with a but. Use input validation, but also use output … [Read more...] about Input validation is less about specific vulnerabilities
Is encoding really encoding if it is escaping?
The title might be confusing, let's see if we can clear it up. I saw an article the other day that was giving a comparison between encoding, encryption and hashing. There was a statement made that basically said: Encoding has no security purpose. I thought this was interesting because when training on security topics we mention encoding for specific use cases. For example, when we discuss Cross-Site Scripting, the answer is output encoding. I want to clarify that I agree with the statement … [Read more...] about Is encoding really encoding if it is escaping?
What is the difference between encryption and hashing?
Encryption is a reversible process, whereas hashing is one-way only. Data that has been encrypted can be decrypted back to the original value. Data that has been hashed cannot be transformed back to its original value. Encryption is used to protect sensitive information like Social Security Numbers, credit card numbers or other sensitive information that may need to be accessed at some point. Hashing is used to create data signatures or comparison only features. For example, user passwords … [Read more...] about What is the difference between encryption and hashing?

Log4J – Reflection and Progression
Open any social media platform or pull up any mainstream media and undoubtably, you have seen many posts/articles talking about the log4j vulnerability. If you haven't seen this, here is a quick link to catch up https://snyk.io/blog/log4j-rce-log4shell-vulnerability-cve-2021-4428/. This post is not going to be about log4j, nor is it going to go into any of the details the thousands of others articles out there would go through. Instead, I want to discuss this at a higher level. Log4j is just an … [Read more...] about Log4J – Reflection and Progression
