Web security is essential for all websites especially for websites that are dealing with confidential information. Websites help with the branding of an organization and it is the first impression for the customer. If the site is not safe and secure, then the website could get hacked and all your hard work will be destroyed resulting in loss of revenue and trust.
Cybercrime businesses are very common these days. Hackers may steal data like credit card information, contact details, username and passwords, and so on. Most of the content management system(CMS) websites are at a higher risk of vulnerabilities and security issues due to the usage of third-party plugins and applications.
Common attacks which can be protected using Website security:
1. Cross-site scripting (XSS): This is a client-side code injection attack that executes malicious scripts in a user’s web browser by including malicious code in a web application or web page. The actual attack takes place when the user visits the web application or web page that executes the malicious code. The web application or web page used for delivering the malicious script to the user’s browser.
2. SQL injection: This type of attack allows the execution of malicious SQL statements. Hackers use SQL Injection to avoid application security measures. This type of website attack is to attain unauthorized access to sensitive information that could include personal data, customer information, and more.
3. Man-in-the-middle (MitM) attack: MitM attack is when a hacker interrupts the communications between a client and a server. Some of the common MitM attacks are Session hijacking and IP Spoofing.
i) Session hijacking: Attacher hijacks the session between a trusted client and a network server. They substitute its IP address for the trusted client while the server continues the session as like communicating with the client.
ii) IP Spoofing: The attacker sends a packet with the IP source address of a trusted host instead of its own IP source address to a target host to accept the packet.
4. Brute force attack: It is also called a password attack. The hacker tries with different combinations of usernames and passwords continuously until it logs into the website. It would take a lot of time when a single computer tries all the combinations, But hackers will use multiple computers or powerful software to make the combinations very easy.
5. DDoS attacks: Denial-of-service attacks are sending enormous amounts of traffic in the network. Example by uploading huge sizes of files into the websites. This will completely crash or slow the website, making it inaccessible to visitors.
6. LDAP injection attack: Lightweight Directory Access Protocol (LDAP) is a software protocol used for intranets. It allows LDAP users to access common resources. An LDAP injection attack is when an attacker in the intranet can send queries without proper validation, which leads to unauthorized data access.
7. Blacklisting: The website could get removed from search engine results, turning visitors away if malware is detected by search engines.
8. Malware: Malware is a very common threat used for distributing spam, permitting attackers to access websites, stealing sensitive customer data, and more.
9. Vulnerability exploits: Hackers can access a website and data stored on it by exploiting weak areas on a website.
10. Defacement: This website attack replaces the web site’s content with malicious content developed by a cybercriminal.
Measures to Improve Security for Websites:
1. Use SSL Protocol.
2. Restrict database access outside the network.
3. Make sure the folder and file have the appropriate read and write permissions.
4. Update Software and plugins regularly.
5. Restrict admin page access from outside networks to avoid search engine indexing.
6. Follow the standards of the Open Web Application Security Project.
7. Regular taking backup.
8. Restrict upload file formats and set a maximum limit for file upload.
9. Include ModSecurity comodo rules in the server.
10. Install web application firewalls — WAF to reduce attack mail from the internet.
11. Changing password regularly and using letters, number, and special characters.
12. Stay updated with the latest cybersecurity information.
13. Make sure Passwords and Access Token are encrypted before storing.
14. Ensure in production logs do not contain any confidential information.
15. Disabling server related information in the HTTP headers.
In today’s scenario, there exists a lot of hacking techniques that are easily available on the internet. To avoid attacks from hackers, we need advanced website protection measures.
We should be more proactive in web security while developing a website.
