Cyber Security Expert, A Challenging Role!
Information security and hacking always had a lot of glamour around them. Many aspire to be Cyber security experts. If you have decided this by watching a movie, hold on. Let us understand what it takes to become a real expert in this field. You will be in demand for a job only if you equip yourself with the required skills.
A study by Burning Glass revealed that the number of cybersecurity job postings has grown by 94% in just six years, and cybersecurity jobs now account for 13% of all information technology jobs.
Cyber Security Expert knows the complete domain
Cyber Security is a domain which spans the entire gamut of software systems. That means, it consists of hardware, sensors, operating systems, network, network devices, servers and so on. As a cyber security expert one needs to be well acquainted with all these parts of the system.
Information security implementation is more emphasized with system-level controls. Today, applications using different technologies are becoming the main focus at enterprise level. Software systems continue to grow and become more complex. As a result, more vulnerabilities are found in the application software. Legacy code and new developing technologies are the reasons that applications may open up additional vulnerabilities which are not yet known.
Vulnerability, Threat, and Cyber Attack
Let us understand some of the key terms.
Vulnerability is a loophole or flaw which can be used by someone with malicious intent to get into the system.
Security threat is a malicious act which can have a bad impact.
A cyber attack is an attempt to exploit a vulnerability with some motive or intention. Generally, this intention is not so good. The intentions typically are disrupting a business, stealing information, manipulating data, damaging reputation, etc.
When one becomes a cyber security expert, he/she needs to be aware of various vulnerabilities and attacks and how to stop them or recover the system.
Common Type of Cyber Attacks
Let us explore common types of attacks.
Viruses and Worms
Viruses and worms are malicious programs that are aimed at corrupting data. They replicate themselves and infect the systems when they get connected.
In phishing attacks, users are lured to click on links embedded in emails. These links take them to websites which ask for personal information or install malware on their device. This way the device gets compromised.
In a distributed denial-of-service or DDoS attack, multiple machines are used to attack a server or website. These machines generate such a flood of connection requests that the target server or website crashes down. Thus legitimate users are denied access to the system.
This is like human kidnapping case and asking for a ransom. Here instead of humans, it is the data which is locked or encrypted by the virus attack. One needs to pay the ransom to get the data back.
APT stands for advanced persistent threat. In this attack, the intruder hacks the network, enters the system and remains under stealth. He/She monitors the activities on the network and uses it to steal highly sensitive data. The hacker remains in the system undetected for a long period of time.
Common security threats range from viruses to APTs or advanced persistent threats. Organization’s cyber security team needs to be ready to handle them. Moreover cyber security threats continue to become more and more sophisticated with technologies. So, the enterprise security team must remain vigilant. If you are a cyber security expert who is trained in Ethical Hacking Course in Pune, you may be able to join these teams and protect organizations. Isn’t it going to be a challenging role?
