Cyber Security Jobs

Here we are explaining what the basic fundamental of cyber security for beginner to expert level guide which can help you to become cyber security expert and get your job in the field of cyber security.

Type of Cyber Security & Tools and the type of cyber attacks being commonly performed by hacker.

Cyber security is practices of protecting computer network, software program, computing resources and IT related equipment from unauthorized digital access and hacking attempt.  

साइबर सुरक्षा:- अनधिकृत डिजिटल एक्सेस और हैकर हमले से कंप्यूटर नेटवर्क, सॉफ्टवेयर प्रोग्राम, कंप्यूटर सिस्टम और आईटी से संबंधित उपकरणों की सुरक्षा करने का तरीका है।

Type of cyber attacks | साइबर हमले का प्रकार |  

1. Malware Attack :- Malware is a very common cybers attack, Trojan, Adware, Spyware, Suspicious Attachment, Virus Mails, Keylogger, Worms, E-mail attachment are the group of malicious software program use to execute “malware attack”.  

मालवेयर अटैक- (ट्रोजन, एडवेयर, स्पाईवेयर, सस्पेंस अटैचमेंट, वायरस मेल, कीलॉगर, वर्म्स आदि मुख्य प्रकार है| 

2. Advance persistent Threat (APT) :- PSU or govt organization usually face Advance persistent Threat (APT) attack, through APT hacker  can get access for prolong period of time. In order to continually gain      access of confidential data. 

3. Denial of Service (DOS) :- DOS attack flood services request using multiple        servers. which stops legitimist service request. Advance version of DOS  is,  Distributed Denial of services (DDOS), where hacker send multiple requests to the resource,  flood the bandwidth result Denial of Service attack to harm the organization.   

4. SQL injection:-  Hacker can manipulate query in database, hacker can view, edit, delete any data in any vulnerable database server.

5. Man-in-the-middle Attack :-  Man-in-the-middle Attack is also      through malware, known as the network attack or eavesdropping attack, where hacker can hijacks session between the client and the server, and capture data during transections due to unsecure public network.  

6. Type of Password attack: 

  • Dictionary attack
  • Brute force (trail and error method), It takes long time using combination and permutation.
  • keylogger attack can capture users typed data. 
  • Shoulder surfing, by looking over the user’s shoulder.

Terminologies of Cyber Security:

1. Network:- Network is a group of devices connected to each other through wired or  wireless. 

2. Server/Client :- Server is a computer hardware or software that provides functionality for other programs or devices, called “clients”. This architecture is called the client–server model.

3. Internet :- Internet is globally connected set of network.

4. Network Protocol :- Network Protocol is the defined set of rules that determine the data connectivity and transmission between devices through internet.  

5. TCP/UDP : If TCP/UDP would not have been there our network would have collapse. 

6. IP address : IP address helps to identify any device or website on internet, IP address is a 32 bit numerical address like (192.168.1.1) assigned to each equipment on network, without IP any device can not connect to the internet.

7. Media Access Control (MAC):- Mac is also called Physical Address of any network equipment (Physical Address: ‎E0-69-95-DE-07-1D it’s a unique identification number that assigned to each hardware in the network. known as physical address and it’s can’t be changed. 

What is cybersecurity ?

Cybersecurity refers to the protection of hardware, software, and data from attackers/hackers. The primary purpose of cyber security is to protect against cyberattacks like accessing, changing, or destroying sensitive information.

Elements of cybersecurity. 

The Major elements of cybersecurity are, Information security, Network security, Operational security, Application security, End-user awareness, Business continuity planning. 

Advantages of cyber security awareness

Awareness of cyber security helps you to  protects your business, organization against ransomwaremalwaresocial engineering, and phishing. It helps to  protects end-users. It gives good protection for both data as well as networks. Increase recovery time after a breach. Cybersecurity prevents unauthorized users.
