Cyber Security Expert, A Challenging Role!

Cyber Security Expert, A Challenging Role!
2

• 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
• Vulnerability is a loophole or flaw which can be
  used by someone with malicious intent to get into
  the system.
• Threat
• Security threat is a malicious act which can have
  a bad impact.

6

• Cyber Attack
• 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.
• Phishing
• 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.

8

• DDoS
• 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.
• Ransomware
• 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. 

9

• APT
• 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.

10

• Common security threats range from viruses to
  APTs or advanced persistent threats.
  Organizations 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. Isnt it going to be a challenging
  role?

• Conclusion
• Many aspire to be Cyber Security Experts. But
  before that let us understand what it takes to
  become a real expert in this field.
