A special request was made today: "How does SSL work? What is an SSL handshake?"

Here are some quick info.

 

SSL/TLS are protocols used for encrypting information between two points. It is usually between server and client, but there are times when server to server and client to client encryption are needed. For the purpose of this blog, I will focus only on the negotiation between server and client.

 

For SSL/TLS negotiation to take place, the system administrator must prepare the minimum of 2 files: Private Key and Certificate. When requesting from a Certificate Authority such as Symantec Trust Services, an additional file must be created. This file is called Certificate Signing Request, generated from the Private Key. The process for generating the files are dependent on the software that will be using the files for encryption.

For a list of the server softwares Symantec has, have a look at:...

Look! I have a lock, I see https://, I even see the Green Bar, I believe I have protected my server and the clients connecting to our services from attackers now. I can't start increasing security and block clients to my site by disabling SSLv3, MD5 or RC4. I'll be losing customers and profit! I can accept a weaker security as long as user traffic and profit are not affected.

 

Performance vs Security is a constant struggle between security experts and management. When it comes to SSL it is no different. Do we allow as many clients to access our site as possible, or do we block all the weak connectivities. There has been numerous studies on this, so I won't go into it here. As a SSL security expert, allow me to take sides this time. Allow me to provide some more gear for us to convince our management why SSL security is more important and how we can migitate the risks without affecting performance or traffic too much.

If you don't care for the details of this blog, there is a Summary at the bottom.

 

Recently I was called, at home, informing me that my computer was “downloading viruses”. This is the fourth time this has happened and so I decided to take notes, screenshots and follow through with what happens.

Just a quick note about my setup; I pretended that my machine was a Windows XP SP2 box, which is actually virtualised and has many snapshots already taken. This means, if required, I can give control to anyone online of this machine without worry. Consequently, whilst the caller was describing my problems, I had created a backdoor to this system that allowed me to control processes from another computer. This meant, if anything TOO bad was about to happen, I can cut them off. I also had to pretend that I knew next to nothing about my computer and that I just used it for web browsing and e-mail.

So, here’s what happened: I received a call at...

Because of its non-centralised nature, PGP key management can be challenging. This is especially true when you are managing your own PGP keys.

Follow the steps below to get up and running quickly with PGP encryption.

Note: The steps below apply to all PGP/GPG clients.

Personal PGP Key Management

  1. Install a PGP client such as Symantec Encryption Desktop
  2. Create/generate a PGP private key
    1. Ensure that you use a strong pasword
    2. Set an expiry date
    3. Set an appropriate key strength
    4. Create a revocation certificate
  3. Create a PGP public key
    1. Export your public key using the following format for the filename: Firstname Lastname firstname.lastname@domain.com (0xFFFFFFFF) pub.asc
      1. Replace (0xFFFFFFFF) with you PGP public key's fingerprint/key id
  4. Distribute your PGP public...

Today SSL is an integral part of online businesses and any secured communication. It is however not an area that many system administrators or security experts are comfortable with. For most administrators the correct installation of the private key and its corresponding certificate is sufficient. As long as the green bar, the padlock, or https:// can be seen during the SSL/TLS negotiation, both the administrators and their clients trust that the connectivity is secure.

 

However many security flaws and vulnerabilities have been discovered in the recent years. From the server side there is the infamous Heartbleed bug or CCS injection - CVE-2014-0224, side-channel attacks such as Beast, Lucky 13, Crime or BREACH, and others (SSL Attack Survey).  It is not sufficient to just have a correct installation of the private key and certificate pair on the server...
