The Cyber Morum

  In this blog, I am going to install configure, and even block a malicious domain in the form of a redhunt.net. We will create rules to block this domain.  You can download the ISO file for the pfsense firewall from this  pfsense website .  Download the FreeBSD version from the  FreeBSD website  and we will set the type as BSD. FreeBSD is a free and open-source Unix-like system and popular server platform. It generally has a lower amount of security issues than Linux and makes it easy to set up a rule-based packet filtering firewall. Now we will ensure that our virtual machine is in the bridged networking mode so that it can use its own IP address and does not have to share it with the host system. INSTALLATION PHASE: After starting the virtual machine you will initially see this screen at the start. After choosing all the default options you will end up on this screen below. You can see it is asking Should VLANs be set up now? we will type "n".  Now ...

After learning about CompTIA security+ through LinkedIn and after doing some initial research about the content, book, and objectives of the exam I got an understanding that this certification touches on every part of the fundamental cybersecurity domain in great detail.

How the certification helps? As we know CompTIA security+ is a global certification it validates and helps us have the baseline knowledge to perform core cybersecurity operations. It helps an individual to identify and address potential threats, risk management techniques, and also intrusion detection and prevention systems among others. As the exam covers 6 important domains within cybersecurity some of the key topics I learned and think were very essential in building up my knowledge...
