In computer science, most of the students choose his/her career as a developer such as a web developer or mobile application development. But, there are lots of job profile after computer science. Such as Bussines Developer Executive, Human Resource, Technical Engineer, Web Developer, Application Developer, Network Administrator, Penetration Tester, etc.
In this blog, I am focusing on a career road map in Cyber Security. In this digital era, Companies are more focusing on security. Suppose, the company hired Network Administrator then they expect that employee has knowledge of networking and awareness of cyber attacks.
Before deep dive in Information Security
- If you’re new to information security, forget everything you know about hacking.
- Don’t start using tools without reading about pen testing and how it works.
- Don’t download and use tools that you don’t audit the code.
- Don’t use these tools to do stupid things like investigating/hacking without consent on your friends, or worst, your recruiter.
- Read books, manuals, articles, be curious and not just a script kiddie.
- I wish you don’t use these tools for illegal purposes, but if you do, I sure hope you know what you do.
What is Penetration Testing?
Penetration testing is a type of security testing that is used to test the insecurity of an application. It is conducted to find the security risk which might be present in the system.
If a system is not secured, then any attacker can disrupt or take authorized access to that system. Security risk is normally an accidental error that occurs while developing and implementing the software. For example, configuration errors, design errors, and software bugs, etc.
Career vocab for Information Security
Infosec : Information security, which is the practice of preventing unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction of information. The information or data may take any form, e.g. electronic or physical. Infosec can also be a person who practices ethical security. Wikipedia
Opsec : Operations security, which is a process that identifies critical information to determine if friendly actions can be observed by enemy intelligence, determines if information obtained by adversaries could be interpreted to be useful to them, and then executes selected measures that eliminate or reduce adversary exploitation of friendly critical information. Wikipedia
Black/grey/white hat hacker : Someone who uses bugs or exploits to break into systems or applications. The goal and the method differs depending if he’s a black, grey or white hat hacker. A black hat is just someone malicious that does not wait permission to break into a system or application. A white hat is usually a security researcher who practice ethical hacking. A grey hat is just in the middle of these two kind of hackers, he might want to be malicious if it can be benefit (data breach, money, whistleblowing …).
Red team : According to Wikipedia, a red team or the red team is an independent group that challenges an organization to improve its effectiveness by assuming an adversarial role or point of view. It is particularly effective in organizations with strong cultures and fixed ways of approaching problems. The United States intelligence community (military and civilian) has red teams that explore alternative futures and write articles as if they were foreign world leaders. Little formal doctrine or publications about Red Teaming in the military exist. In infosec exercises, Red teamers are playing the role of attackers. Wikipedia
Blue team : A blue team is a group of individuals who perform an analysis of information systems to ensure security, identify security flaws, verify the effectiveness of each security measure, and to make certain all security measures will continue to be effective after implementation. As a result, blue teams were developed to design defensive measures against red team activities. In infosec exercises, Blue teamers are playing the role of defenders. Wikipedia
Penetration tester : An ethical hacker who practice security, test applications and systems to prevent intrusions or find vulnerabilities.
Security researcher : Someone who practice pen testing and browse the web to find phishing/fake websites, infected servers, bugs or vulnerabilities. He can work for a company as a security consultant, he is most likely a Blue teamer.
Reverse engineering : Reverse engineering, also called back engineering, is the process by which a man-made object is deconstructed to reveal its designs, architecture, or to extract knowledge from the object. Similar to scientific research, the only difference being that scientific research is about a natural phenomenon. Wikipedia
Social engineering : In the context of information security, it refers to psychological manipulation of people into performing actions or divulging confidential information. A type of confidence trick for the purpose of information gathering, fraud, or system access, it differs from a traditional “con” in that it is often one of many steps in a more complex fraud scheme. The term “social engineering” as an act of psychological manipulation of a human, is also associated with the social sciences, but its usage has caught on among computer and information security professionals. Wikipedia
Threat analyst : A threat hunter, also called a cybersecurity threat analyst, is a security professional or managed service provider (MSP) that proactively uses manual or machine-assisted techniques to detect security incidents that may elude the grasp of automated systems. Threat hunters aim to uncover incidents that an enterprise would otherwise not find out about, providing chief information security officers (CISOs) and chief information officers (CIOs) with an additional line of defense against advanced persistent threats (APTs).
CISO : A chief information security officer (CISO) is the senior-level executive within an organization responsible for establishing and maintaining the enterprise vision, strategy, and program to ensure information assets and technologies are adequately protected. The CISO directs staff in identifying, developing, implementing, and maintaining processes across the enterprise to reduce information and information technology (IT) risks. The CISO is also usually responsible for information-related compliance (e.g. supervises the implementation to achieve ISO/IEC 27001 certification for an entity, or a part of it). Wikipedia
CIO : Chief information officer (CIO), chief digital information officer (CDIO) or information technology (IT) director, is a job title commonly given to the most senior executive in an enterprise who works for the traditional information technology and computer systems that support enterprise goals.
