by admin | Jul 12, 2024 | Blog News - English, Website Monitoring, Website Security, Website Suspension

Unsettled Bills

A website can be suspended due to unsettled bills related to that domain or website. It can be web hosting annual fee, domain registration fee, the website design charges not paid or other critical reasons

Violation of server terms and conditions

The website can also be suspended if it violates server terms and conditions. These terms vary according to the host but common ones are:

1. Email spamming
2. Server resource over usage eg. Over CPU usage, physical memory over use, Virtual memory over use, too many processes normally over ten (10) processes etc
3. It can also can be suspended if it is under attack or hacked. The hacking can originate from admin or backend access, database injection or cross platform scripting.

How is the website attacked?

Backend or Administrator access

The access through the backend are normally caused by using either weak password, common words, and easy to guess usernames.  

SQL Injection

SQL injection is a code insertion method, used to attack database-driven web applications, in which evil SQL statements are inserted into an entry field for execution (e.g. to dump the database contents to the attacker).

Cross-site scripting -XSS

Cross–site scripting (XSS) is a kind of computer security hole typically found in web applications. XSS allows assailant to insert client-side scripts into web pages viewed by other users.  This is normally used for phishing, stealing users important information like passwords and credit card numbers

Bugs

A scrip bug is an error, flaw, failure or fault in a web application that causes it to allow attacker insert harmful codes/commands to that applications  

Poor coded scripts

Poorly coded scripts in many cases originate from students who are still learning or from developers with insufficient coding skills and experiences. The poor coded scripts can also originate from pre release software or beta

Cross-Site Request Forgery (CSRF)

Cross-site request forgery is abbreviated as CSRF is a type of harmful exploit of a website where unlawful commands are sent from a user that the web application trusts.

DDoS Attack

A distributed denial-of-service(DDoS) attack takes place when multiple systems flood the bandwidth or resources of a targeted server, usually one or more web servers. Such an attack is often the result of multiple compromised systems (for example, a botnet) flooding the targeted system with traffic.

Server security misconfiguration

Security Misconfiguration arises when Security settings are defined, implemented, and maintained as defaults. Good security requires a secure configuration defined and deployed for the application, web server, database server, and platform.

Email spamming

There are two types of email spamming

1. Bulk emails are sent to your email server from unanimous senders
2. Bulk email are sent to third parties in bulk via your email server by spoofing means

How to protect your website from Attacks

Backend or administrator access

Always use difficult to guess usernames and strong passwords. Password from 8 and above characters that contains at least 4 character types from Capital, small letters, numbers and special characters can reduce the risk.

Parallel to this deploy to your website login attempt limiters and firewalls. This can reject all dictionary or related bots that guess your username and passwords.

Implement also webmaster reporting mechanism if something changes from your website. You may go far by limit logins from know IP addresses or countries. If you don’t have any deal to specific country, then block your website from appearing from those vulnerable countries. If at all you don’t need public presence then block search engine bots and any other bots from visiting your website

SQL Injection

You may need to use difficult to guess usernames and password for your database.  Password from 8 and above characters that contains at least 4 character types from Capital, small letters, numbers and special characters can reduce the risk. Implement webmaster reporting mechanism if something changes from your database. You may go far by limit logins from know IP addresses or countries. If you don’t have any deal to specific country, then block your website from appearing from those vulnerable countries. If at all you don’t need public presence then block search engine bots and any other bots from visiting your website

Cross-site scripting -XSS, Bugs,

Buy scripts from reputable and known providers. Avoid cheap scripts. Also deploy backend security mechanism as described above. For script with bugs that are from known genuine vendors or developers, pl;ease make sure you immediately update all outdated scripts or uninstall if the vendor did not release the update patch on time    

Poor coded scripts

Buy scripts from reputable and known providers. Avoid cheap scripts. Also deploy backend security mechanism as described above

Cross-Site Request Forgery (CSRF)

Always deploy security monitors, scanners and blockers for unauthorized outbound and inbound communications

Server security misconfiguration

Check your server configuration regularly and if any misconfiguration detected correct it and or communicate to the server admin/ tech personnel for correct configuration. In many cases let the web server have the optimal security setting

DDoS Attack

1. The best way to stop DDoS Attack is tto use the web application Firewall
2. Monitor the DDoS Attack continuously in order to device the better option of preventing the attack

Email spamming

There are two types of email spamming

1. Bulk emails are sent to your email server from unanimous senders
2. Bulk email are sent to third parties in bulk via your email server by spoofing means

Protect bulk emails spamming from unanimous senders

For the first case you can use mails assassin

Protect bulk emails spamming via you email server

For the second case you can use SPF or disabling PHP Mail function in cpanel

Using SPF to control email spoofing and phishing

Adding an SPF record to your DNS zone file is the best way to stop spammers from spoofing your domain. In addition, an SPF Record will reduce the number of legitimate e-mail messages that are flagged as spam or bounced back by your recipients’ mail servers.

This is an easy way to control phishing and email spoofing.

Disabling PHP Mail function in cpanel

1. While in Cpanel go to Software section
2. Select PHP Version
3. Switch to PHP Options
4. in send mail path select /bin/true
5. Then click apply and save the PHP setting
