The importance of forensic computing
23 / 11 / 2015
Nowadays, in addition to the protections we have at our fingertips such as antivirus and other security software, we also have other alternatives that, in a certain way, increase the security of our IT systems, and among these alternatives is forensic computing.
As experts explain, forensic computing is a science that consists of the acquisition, preservation, collection, and presentation of data that has previously been electronically processed and stored on a physical storage medium.
Its objective is to investigate information systems to detect any type of evidence of vulnerabilities they may have. It also pursues different prevention objectives, trying to anticipate what might happen as well as establish a quick solution when vulnerabilities have already occurred.
At our company for IT maintenance in Barcelona and Madrid, we know that the role of forensic computing is mainly preventive. It helps us, through different techniques, to prove that the security systems we have implemented are adequate so we can correct errors and improve the system, in addition to developing security policies and using certain systems to improve both the performance and security of the information system.
If the security system has been bypassed, forensic computing allows us to trace and detect not only how the system was bypassed (which will help patch that flaw to prevent it from happening again) but also to determine the level of damage the threat has managed to cause.
It also allows the collection of electronic evidence, detection of where the attack originated, or whether any changes have been made to the system, such as manipulation or theft of data, installation of malicious files, alteration of hard disk files, etc.
This has become an indispensable science for the IT security of many companies and also a great ally for state security forces, as it also enables the collection of evidence found to locate and arrest the person or people who have accessed an IT system without authorization, those who steal confidential information, or delete data, etc.
Since nowadays the value of sensitive data and information, whether it comes from governments, companies, or individuals, is increasing, it is very important to protect it as much as possible. For this reason, forensic computing has become one of the most reliable allies, which is why periodic audits of systems are necessary.
Likewise, something that must be taken into account is that it is really necessary to establish security policies for all users as well as for the use of information systems, in order to reduce as much as possible the likelihood of any kind of security failure or \"open door\" occurring due to user error.
