The cybersecurity has gained uttermost importance in the contemporary era of constant cyberattacks around the world. Many cybersecurity firms have ultimately come up with numerous steps to counter cyberthreats before, during and after the cyberattacks. One of the most popular and effective sets of steps prescribed and known as SANS methodology is followed worldwide by governments as well as non-government private cybersecurity firms such as Elijah cyber due diligence and most individual users which have the potentiality of quickly and efficiently recover from cyber-attacks if already occurred.
The basic purpose of these systematic steps is to help the victims to effectively and systematically respond to the incident at an appropriate time. Eventually, the steps or the measures have the potentialities to minimise the theft or loss of data or to reverse the disruption of services after the attack. The types of cyberattacks can be numerous out of which some may be familiar, and some may not because day by day the hackers coming with new types of threats and attacks. Some of the familiar attacks may be malicious code attacks, espionage, denial of services, sabotage, unauthorised access, hoaxes, violations of policies, insider threats and many more. The recommended steps of SANS namely preparation, identification, containment, eradication, recovery and lesson learned are consciously prepared for all possible attacks.
The steps begin with preparation where you develop your response capacity involving roles and responsibilities at the level of the organization. The preparation guides you how you should engage the professional experts with an appropriate set of skills who can handle the attacks with appropriate tools. The preparation also instructs you whom to approach and what to tell one your system is attacked by the hackers.
The second step educates you about the identification of the attack or how and using which method the hacker has attacked your system. Ultimately, the security mechanism will help you to accurately identify what type of attack the hackers performed with your system. It is here you should observe and identify at what level the attack is such as at the level of network or host or system and can leverage the alerts. At the step of containment, you are taught to respond to the incident so that you can limit the damage and eventually stop the attacker. The next step instructs you how to eradicate the cause of the attack or removing the virus if it is a virus attack. The fifth step is the recovery which educates you how to bring back your system into normal functioning.
