Network Security

Network Security:

Network security is the policies and procedures implemented by a network administrator to avoid and keep track of unauthorized access, exploitation, modification, or denial of the network and network resources. It also consists of the policies and practices adopted to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. This means that a well-implemented network security blocks viruses, malware, hackers, etc. from accessing or altering secure information.

Why Your Business Need Robust & Reliable Network Security?

  1. Decrease the chance of privacy spoofing, identity or information theft of your business assets and clients
  2. Prevent financial loss due to information security breach
  3. Avoid both potential customers’ lawsuits and government fine due to violating data privacy protection

There are Several Types of Cybersecurity Attacks on Network Security:

    • Botnet
    • Data Modification
    • Unstructured
    • Structured
    • Email Phishing
    • Dos DDOS Attacks
    • Password Attacks
    • IP Address Spoofing

 

Botnet:
A collection of bots, or software that creates a list of infected computers, which are controlled by the hacker. It can send spam email with virus attached, spead all types of malware, and even use your computer as part of a denial of service attack against other systems


Data Modification:

After an attacker has read your data, the next logical step is to alter it. An attacker can modify the data in the packet without the knowledge of the sender or receiver. Even if you do not require confidentiality for all communications, you do not want any of your messages to be modified in transit. For example, if you are exchanging purchase requisitions, you do not want the items, amounts, or billing information to be modified.


Unstructured Attacks/Threats:

An unstructured threat refers to a computer attack from novice hackers, often called script kiddies, who use software created by more advanced hackers to gain information from or access to a system or launch a denial of service attack.


Structured Attacks/Threats:
Known as Structured Threat Information eXpression, aka STIX,  is a standardized XML programming language for conveying data about cybersecurity threats in a common language that can be easily understood by humans and security technologies.

Email Phishing:
As one of the most common hacking attacks, email phishing is typically a fraudulent email message that appears to come from legal enterprises. The email looks legitimate and may even lead to a spoofed website. The aim of this email phishing is to attain private information (including password, credit card, bank account, medical, and financial). Aimed at inducing panic in the reader, the hacker will often use an email with immediate respond request, by claiming they will lose something if an action is not taken. Hacker uses the attained information to commit identity theft or even illegal purchases.

Examples include IRS refund request, court notice to appear, job listing, tax request, and bank account change confirmation.


Dos & DDOS Attacks:

DoS & DDOS (AKA – Denial of Service and Distributed Denial of Service) attacks take advantage of network traffic to create an abnormal behavior to network services or applications. Servers are often targeted and flooded with data until they become unreachable. Core network equipment can be blocked and thus prevent normal traffic from flowing into the network. Distributed denial of service attacks is more dangerous because attacks are made from multiple sources.


Passwords Attacks:

Password attacks are based on cracking user or equipment passwords. They are one of the most feared network attacks because once a user is compromised, the whole network can be damaged, especially if we are talking about a domain user or network administrator.


IP Address Spoofing:
Hackers use spoofed IPs to impersonate a legitimate machine. The attacker can then modify packets making them look like legitimate traffic to the receiving network device.
