One of the most thrilling jobs in the IT sector is becoming a cybersecurity expert. It holds excellent prospects to learn plenty of interesting tactics and is always high in demand. Another advantage is that it fetches high salaries and holds great prospects for promotions.
If you are looking to become the Cyber Security Expert, then it is always best to understand a few of the important things and the road that you will take ahead.
The basis of cyber security lies in the understanding of networking to make its way into this field. One is expected to get acquainted with the topics like Subnets, TCP/IP, IP address, Ports, Mac address, hubs, network layers, switches, etc.
Once you unlock the basic knowledge, you can foray into the basics of specific cyber security topics that include learning about Linux, python training, ruby programming, Trojans, viruses, worms, phishing, understanding securing system, information gathering, etc. This is the first step towards entering the cyber security field. And after thorough knowledge on these topics, one can be confident enough to understand deep-rooted theories and implications of cyber security.
How to build secured networks
The key feature of any cyber security professional is to ensure a secure network that can eliminate all possible threats. Building a secure system is the sign of a highly professional cybersecurity specialist. Any cyber security personnel would then look to implement security in the following manner to protect the network under his/her control from attacks.
Implementation: The first step towards a robust, secured network lies in implementing a network security system that ensures protection and posses a sufficient amount of authorization policies.
Analyzing: Once the network security system is created and implemented, the cyber security expert system need to analyze the network. This helps in determining whether the existing security system is suitable for the network and is it good enough to protect the integrated systems.
Testing: The first thing is to have an appropriate (based on requirements) network security system in place. Once that is done, the cyber security personnel need to conduct tests to ensure the well-working of all the implemented securities. This in turn demands a certain responsibility to thoroughly protect the assigned network against any possible threats.
Modify: The last step to ensure a secure network after conducting necessary tests is to collect the data and further augment the protections. The data collection will show results revealing where the implemented security system is effective and in what all areas it requires improvement. And since hackers are expert in improvising their attacking abilities, the job of a cyber security expert lies in testing the system as frequently as possible to ensure all-around protection that makes one stay a step ahead of those hackers.

How Security Industry Functions
The growing uses of the internet and system information make things easier for hackers to penetrate multiple areas. And for this reason, the Cyber Security Market is expected to garner $198 billion by 2022, with a CAGR registration of 15.5 % during the forecast period 2016-2022.
The Cyber Security Industry deals with the solutions like Unified Threat Management (UTM), security incident management, risk and compliance management, and even Identity and Access Management (IAM). All of these help organizations to secure their system infrastructure and data from potential harmful cyber threats and vulnerabilities that arise over time. It is the rise of mobile device usage, and reliability on Internet services retail, BFSI, healthcare, and energy that aids the market growth.
This industry is segmented and penetrated at many levels. If we are the classify them, it can be done so into the following umbrellas
– Identity and Access Management (IAM),
– Risk and compliance management, encryption,
– Data Loss Prevention (DLP),
– Firewall, antivirus/antimalware,
– Intrusion Detection System/Intrusion Prevention System (IDS/IPS),
– Security and vulnerability management
– Distributed Denial of Service (DDoS) mitigation,
– Web Filtering
– And others like application white-listing, patch management, etc.
Ethical hacking to tackle cyber security threats
There is always a way to tackle problems. The same has to be done in the matter of cyber security. And the critical solution to such issues lies in Ethical Hacking.
Ethical hacking is a non-destructive, “white hat” form of hacking, where one has all the means at their disposal. The aim is to gain back access to the system. Consider an example of how to regain the credentials’ access. Here, one can use social engineering techniques and phishing. Other techniques include standard penetration testing techniques like port scanning and scrutinizing the operating system for possible vulnerabilities.
One of the other ethical hacking techniques is called penetration testing which is more of a formal test cycle. Here the organization is aware of the testing that’s happening such that it can merge to be a part of a development life cycle. Last year it was reported that the NHS plans to implement ethical hacking to secure its defenses.
Be it a black hat or a white hat tactic, it helps create an ethical quandary ensures for the cyber security industry. This ensures that cyber security for any company needs the same level of skills to destroy threats.
