From Vulnerability Found, To Patched Safe

 

While we are preparing for the holidays and the New Year, may it be Christmas/ Hanukkah or otherwise, the hackers are also busy prepping for their busiest time of the year. Although the Holidays is a season to be jolly, it is not a reason to slack off in keeping up with your Cyber Security.

The following image shows a potential timeline of when a vulnerability is found, disclosed to public, Anti-virus software rewritten, patch released, and patch installed.

Notice there is a number of days with no defense in your machines, and that is why a patch that is released should be installed soon.

Why do we say that hackers are also busy? This is because when people tend to lower down their guard, thinking that everyone is busy with the flow of the season, it is also the time that our Cyber protection becomes lenient and weak. When the defense turns less, then the attacker works harder to find these weakness and then it snowballs.

The reason for the easy attacks by the criminal hackers is because we become complacent and do not patch vulnerabilities when we should, and as you can see the vulnerability has been known by the wily attackers for some time… which makes time your enemy.

 

Ever seen a honeybee hive? The bees defend their hives vigorously, regardless of the time of day or season of the year. They attack-to-defend, to secure the hive at the slightest sense of a perceived threat. That is how optimal your Cyber defense should work. That is how wide your Cyber security should be manifested. It should cover all impact levels and all angles whether the threat may be old or new, small or huge.

 

Just like the bees, to keep your system up to date in “sensing perceived threats”, regular sweep and periodic re-enforcement of defenses must be done by updating your system patches. Before running any computer patches on your system, it is always a good decision to perform a system backup at a certain point. This is for you to be able to reset your systems at its most recent format should the patch go bad in the middle of its installation.  Keep in mind that a patch is a fix to system vulnerabilities (that has been out for months), and it is only now that a fix has been created. Although it took time to create the patch, it is still imperative that the patch be run to ensure that probable threats to your system are reduced if not totally eradicated; and for your computer to work properly improving its performance and usability.

 

Question is, how do you know which patch to run? This depends on the probable risks you are able to determine, based on the major threats and concerns you have sited. To illustrate in a process map, think of it this way:

 

  1. Determine the major threats to your working system. Major threats are external forces that you have no control of, that may interrupt or invade your secure cyber space. This may include:

 

  1. Unauthorized access
  2. Insider threat
  3. Data loss due to external sharing
  4. Insecure interfaces
  5. Fraud / Hijacked accounts

 

  1. Next, determine the major concerns that you need to work on to defend your system against the major threats. Major concerns are the areas that cover the major threat and of which you have the capacity to control. Examples are:

 

  1. Data Loss / Leakage
  2. Privacy and confidentiality of information
  3. Legal and regulatory compliance
  4. Compromised security

 

  1. Identify the impact of the threats and the likelihood that they will occur affecting your major concerns. This depends on your usage to the system. These are the magnitude of the identified Risks that you need to work on. Remember the formula for risk analysis as:

 

Risk = Likelihood * Impact

 

The higher the impact of the major threats, the higher the risk factor.

 

  1. Determine the controls and oversite that you need to work on and improve/update your network processes to fix or to be ready to defend your systems aggressively. This is where necessary patching comes in.

 

Since patching is a strenuous process (doing back up, uninstalling all system instances, then patching), it is where most people slack off. You cannot expect not to be robbed if the gate of your house is closed but the front door is open. It may take a while getting used to checking for bug fixes, but vigilance is the key to reducing risks.

 

So if we patch less (due to holidays or otherwise) and we are not as vigilant as we should be amidst the season break, then … you can expect that Hackers are indeed getting busy.
