What is Cyber Security?

A Textbook Definition would be:

“Protection  of internet connected systems, including  hardware, software and data from unauthorized access”. The unauthorized access may compromise one or more of the following.

  • Integrity of data or information stored
  • Confidentiality
  • Availability of service e.g. where you can’t access a website etc.

The First Ever Cyber Attack: Creeper

IT was written by Robert Thomas without a malicious intent. The virus was designed for an experiment on the Tenex operating system. The virus was intended to replicate itself and display “ Catch me if you can”; instead the virus would remove itself from the machine and travel to the next tenex system.

Cyber Threat Statistics

  • Cybercrime damage to hit $6 Trillion by 2021
  • Average cost of data breach: $3.86 million
  • 48% of the business in U.K identified atleast one cyber attack monthly
  • 74% of the breaches in Q1 2019 are due to passwords being exposed in public
  • 56% of the cyber breaches took one month to discover

Framework

  • Basic Security Framework
  • Types of Security Attacks
  • Types of hackers

Cyber security as opposed to popular belief is more than hacking, its encompasses the following three aspects:

  1. People: This is as simple as using a strong password with numeric, special characters and not related to the user name. How many times do people keep passwords as : Password@1234 or rajnish@121. This is where the maximum mistakes happen, hence awareness and best practices used by people is of critical importance for a strong cyber security preparedness.
  2. Process: According to a report 43% of the cyber breaches happened with small business. The data is not surprising, since these small businesses will lack process in three fronts: Monitoring, Respond, Mitigate. A simple process flaw could be as simple as deactivation of company email ID’s after the employee has exited, a two days delay could damage big data losses for the company.

Technology: Given that people and process are in place, technology can aid in leveling up the cyber defense for an organization. Some of the technology includes Firewalls, DNS Filtering, malware protection, antivirus software and email security

Types of Cyber Attack

Malware

Malware is a term used to describe malicious software,  including spyware, ransomware, viruses, and worms.

Malware breaches a network through a vulnerability, typically when a user clicks a dangerous link or email attachment that then installs risky software

Once inside the system, malware can do the following:

  • Access to key components of the network (ransomware)
  • Installs malware or additional harmful software covertly obtains information by transmitting data  from the hard drive (spyware)
  • Disrupts certain components and renders the system inoperable

Phishing

Practice of sending fraudulent communications that appear to come from a  reputable source, usually through email. The  goal is to steal sensitive data like credit card  and login information or to install malware on  the victim’s machine. Phishing is an  increasingly common cyberthreat.

Man in the Middle

Also known as eavesdropping attacks, they occur  when attackers insert themselves into a two-  party transaction. Once the attackers  interrupt the traffic, they can filter and steal  data.

DDOS

A denial-of-service attack floods systems,  servers, or networks with traffic to exhaust  resources and bandwidth. As a result, the  system is unable to fulfill legitimate requests.  Attackers can also use multiple compromised  devices to launch this attack. This is known as  a distributed-denial-of-service (DDoS) attack

Zero Day Exploit

A zero-day exploit hits after a network  vulnerability is announced but before a patch  or solution is implemented. Attackers target  the disclosed vulnerability during this window  of time. Zero-day vulnerability threat  detection requires constant awareness.

Types of Hackers

Cyber Security Process


To put it in a simple analogy, consider the Covid situation. You need a overall policy first on handling a crisis and a response strategy in the event of a health crisis- which is done by cyber security managers and architects. While in the ground there is a team which continuously monitors travelers coming from various countries and making sure they can pick up any imminent infected people. Next step is assessing the situation on a continuous basis, analyzing the data of infected people and identifying the root cause of the virus infection. The next step is to find solutions to contain the virus using either by developing medication or consider in our case a lock down. Once the entire situation comes under control you continuously audit the entire process to find inefficiency or loopholes.
