10 Steps to Strengthen Web Security in Network Security

Cyber attacks increase daily, so we need to defend ourselves against cyber attacks. Just increase the knowledge that helps you to safe cyber attacks. So let’s learn about web security in network security.

Web security is a part of network security that helps you protect websites, web applications, your phone, and web users from cyber attacks.

Web security in network security involves applying various methods. It ensures that data is confidential, protected, and encrypted.

Web security also relies on cryptography. It is a method of encryption and decryption of data or information.

Importance of Web Security in Network Security

1. Network security helps protect data such as credit cards, personal data, etc.
2. Network security helps businesses in several ways, and increases stability and trust.
3. People’s privacy is one of the major concerns. So Privacy, consistency, and availability are the three main objective
4. Network Security ensures the authorized user has easy and secure access.
5. It prevents security breaches.
6. Network security is essential for compliance with regulations such as HIPAA, PCI DSS, FISMA, SOX, and others.

Role of Web Security in Network Security

• Web security is a subset of network security. It focuses on protecting websites, web applications, and web users from cyberattacks and data breaches.
• Web security is very important because it helps to ensure the confidentiality of web data and services.
• It also makes a defense to make sure about no data breach.

Understanding Web Security

1 Definition of Web Security

Web security is a technique to protect networks and computer systems from web-based attacks.

It involves cyber security, cloud security, web application security, and VPN security.

Significance of Web Security in Network Security

Web security is essential for data privacy, business protection, and saving your data.

It protects you against cyberattacks that use email phishing, and web channels which involve 99% of successful data breaches.

Web Security in Cryptography: Ensuring Confidentiality and Integrity

• Web security in cryptography is the application of cryptographic techniques to protect web data and services from unauthorized access.
• Cryptography is a method of encryption and decryption using algorithms and keys. It ensures the protection of data.

Examples of web security in cryptography

1. Encryption algorithms for web data- These are methods that transform plain text data into unreadable ciphertext using a secret key.
2. For example, AES, DES, and RSA are common encryption algorithms used for web security.

SSL/TLS protocols

1. SSL/TLS protocols ensure the protection of the website through encryption.
2. SSL Protocol establishes a secure connection between the user and the web servers using? HTTPS certificates.
3. For example, HTTPS is a protocol that uses SSL/TLS to secure web traffic.

Digital signatures for web authentication

1. It is generating a signature using a private key and verifies it using a public key.
2. For example, S/MIME is a standard that uses digital signatures to secure email messages.

Network Security Systems

Components of Network Security

1. Firewalls
2. Network access control (NAC)
3. Intrusion detection and prevention systems (IDPSs)
4. Virtual private networks (VPNs)
5. Application security
6. Email security
7. DDoS mitigation
8. Cloud access security broker

Tools for Web Security in Network Security

1. Web Application Firewalls (WAFs)

A WAF or web application FIrewalls is a firewall application that filters network activity. It is a tool that protects Web applications from cyberattacks by filtering HTTP traffic and preventing DDOS attacks.

How does a WAF work

It operates and is filtered through a set of rules or policies. The main function of the WAF is to block malicious traffic and allow only legitimate users.

It blocks automatically inflected data on the web servers. A WAF can use a blocklist, an allowlist, or a hybrid security model.

Types of WAFs- The types of WAFs are based on a network-based, host-based, or cloud-based solution.

1. Filtering Traffic and Preventing Attacks

• WAFs makes a set of rule that are used to block malicious traffics, and also help to block DDoS attacks.
• It protects APIs by filtering traffic and application-layer attacks such as DDoS, SQL injection, cookies manipulation, XXS attacks,
• WAFs set the policy so they protect the systems.
• A WAF can be implemented as a network-based, host-based, or cloud-based solution.

Example: ModSecurity

ModSecurity,

It sometimes called Modsec, is an open-source web application firewall (WAF). It is designed for the Apache server. It is developed on GitHub

Secure Sockets Layer (SSL) Certificates

• SSL, or Secure Sockets Layer, is an encryption-based Internet security protocol.
• It was first developed by Netscape in 1995. SSL is a modern type of TLS method. How it works:

1. Establishing Secure Connections

SSL initiates an authentication process. It is called a handshake between two communicating devices. It ensures that both devices are connected safely.

Internet Security and Web Security: Bridging the Gap

Web security refers to protecting networks and computer systems from hackers when they attack through web servers.

Whereas Internet security is the practice of protecting devices, data, and programs against unauthorized access. This also includes the protection data privacy of a user.

How Internet Security Enhances Web Security

Web security and internet security are often used interchangeably. Web security refers to protecting networks and computer systems.

Protection of a virtual private network (VPN) also comes under web security.

1. Protecting Against Phishing Attacks

Internet security suites help to protect against phishing attacks by checking incoming emails if any suspicious links in them.

The common attack by Hackers is email So protecting emails is essential.

2. Securing Online Banking Transactions

Internet security software checks the website’s URL before open by the users. SO ensure your opening website is safe or not.

Web Security Examples: Learning from Incidents

Data Breach Due to Weak Web Security

Cybersecurity is never easy so always aware of it. Here are some examples of data breaches due to Weak Web Security:

1. Equifax Data Breach

Equifax is one of the three major credit reporting agencies in the USA. In September 2017, Equifax announced a data breach that exposed the personal information of 147 million people.

2. Lack of Patch Management and Consequences

When a Software developer makes software, never be completely safe. SO patches are required from time to time to ensure the security and stability of the system.

The patch is the security file that removes vulnerabilities in the system before recognized by hackers.

Microsoft releases every month patched to WIndows to ensure the safety of devices.

Google’s Bug Bounty Program

Google?s Bug Bounty Program is a program that rewards security researchers who discover and report vulnerabilities in Google?s products and services.

As part of the program, Google offers bug bounty payouts of up to $31,337 for vulnerabilities found in its open-source projects

7 Steps to ensure web security in network security

1. Use Secure Passwords

There are many password managers available to remember our passwords. Use a strong password to access your application.

2. Emails

Many phishing attacks appear in emails. Emails are a soft target for hackers, so get help from an Anti-virus program to check malicious links in emails.

3. Install Software Updates

Keeping up to date is one of the best methods to ensure safety.

4. Use a Secure Network Service

Don’t go for cheap, useless hosting. Buy always-trusted services to get security for your web.

5. Encrypted Data

SSL secures the established connection between the server to users. It is encrypted when data flows to users and to a web server.

7. Run Regular Security Checks

Security vulnerability scanning must be regular to check any vulnerability. It helps to stabilize your network security.
