American Cryptology during the Cold War, 1945-1989 ( NSA).Differential cryptanalysis ( Wikipedia).The Data Encryption Standard (DES) and its strength against attacks by D.NSA’s involvement in the design of the Data Encryption Standard ( Wikipedia).The Visual Microphone: Passive Recovery of Sound from Video ( YouTube).Smashing The Stack For Fun And Profit ( ).For Everyone – PagerDuty Security Training ( ).For Engineers – PagerDuty Security Training ( ).Data remanence: This is when an attacker gets sensitive data after it was thought to have been deleted.Acoustic cryptanalysis: This is when the attacker is analyzing sounds to find out what’s going on, such as using a microphone to listen to the sounds of typing a password.An example of this process is called differential power analysis. Power analysis: This is when you can actually figure out what a processor is doing by analyzing the electrical power being consumed.For example, multiplication takes longer than addition so you might be able to determine that there’s multiplication happening. Timing attack: Understanding how long certain processes take can allow you to infer information about the process.Side Channel Attacks: This is when the attacker is using information that’s not necessarily part of a process to get information about that process.You need to run scans on your apps, code, and infrastructure. Remember, your dependencies may also have vulnerabilities such as this.Path Traversal: This is when you “break out” of the web server’s directory and are able to access, or serve up, content from elsewhere on the server.Apparently you can use this method to easily get a root shell – article linked in the resources.

One malicious use of a buffer overflow is using a NOP sled (no-operation sled) to fill up the buffer with a lot of NOPs with your malicious code at the end of the ride.Typically these are used to execute malicious code by putting instructions in a piece of memory that is to be executed after a previous statement completes.From Wikipedia, a buffer overflow _”is an anomaly where a program, while writing data to a buffer, overruns the buffer’s boundary and overwrites adjacent memory locations.”_.Buffer overflow: This is when a piece of data is stored somewhere it shouldn’t be able to access.Use the least permissive approach you can as it greatly reduces risks.

If you need to delete files from a storage bucket, have a service account or user set up with just that permission.

Create separate users for separate needs.

more restrictive permissions, as in, can you live with read-only perms?

The the principle of least privilege, i.e.

If you can’t avoid it, use it with care.

Try to avoid using sudo in any shell scripts if you can.

When a user logs out or the session expires, ensure you fully destroy all session information.

This should be completely independent of the cookie because the cookie values can be manipulated.

Make sure you have an expiration that is set on the server side session.

Always keep information stored on the server side, not on the client.

To avoid the session fixation we mentioned earlier, ALWAYS make sure to send a new session ID when privileges are elevated, i.e.

The domain is set on the cookie so it can only be used by your application.

Ensure the following when sending cookies to the client:.

Session ID’s should be unique and random.

All of this just catches the easy stuff.

Make sure it hasn’t expired and ensure you set expirations for sessions.

Ensure you actually created the session.

Add extra pieces of data to the session you can verify when requests are made.

Always treat cookies like any other user input, don’t implicitly trust it, because it can be manipulated on the client.

This used to be more of an issue when session tokens were passed around in the URL (remember CFID and CFTOKEN?!).

Session fixation is when a bad actor creates a session that you will unknowingly take over, thus giving the bad actor access to the data in the user’s session.

Taking over cookies that weren’t properly locked down.

Guessing or stealing the session identifiers, or.

Session hijacking is stealing a user’s session, possibly by:.

Besides tampering, it can be difficult to revoke the cookies.

Do NOT store sensitive information in the cookie, such as no usernames, passwords, etc.

They usually contains a session token of some sort, which should be a random unique string.

Cookies are commonly used to store information on the client to be sent back to the server on subsequent requests.

HTTP is stateless, so there needs to be a way to maintain state.

Session management is the ability to identify a user over multiple requests.
