The majority of website breaches involve attempts to use a server as an e-mail relay for spam or to set up a temporary web server to serve illegal files. Participating in botnets and mining bitcoin are other common methods by which compromised computers are hijacked. It can also be infected with ransomware. Hacks are often performed by automated scripts that crawl the Internet and exploit vulnerabilities in known website software. Here are 5 tips to keep you and your website safe online.
Keep your software updated
It may seem obvious, but keeping all your software up to date is crucial to keeping your website secure. This applies to both server operating systems and software on websites. When vulnerabilities are discovered in software, hackers quickly exploit them.
Beware of SQL injection
A SQL injection attack occurs when an attacker attempts to access or tamper with a database using the web form fields or URL parameters. Using standard Transact-SQL, it’s easy to inadvertently inject malicious code into your queries that can be used to modify tables, retrieve information, and delete data. This is easily avoided by always using parameterized queries. Most web languages support this and it’s easy to implement.
Avoid error messages
Be careful not to provide too much information in your error messages. Only provide minor bugs to users so they don’t reveal secrets on your server. Also, don’t expose all the exception details as it can greatly simplify complex attacks such as SQL injection. Keep detailed error logs and show users only the information they need.
Validate both sides
Validation should always be done on both the client and server sides. Leaving a required field empty or entering text in a purely numeric field allows the browser to recognise it. However, these can be circumvented, so you should check this and perform deeper validation on the server side. Otherwise, malicious or script code could be injected into your database or cause undesirable results on your website.
Avoid file uploads
Allowing a user to upload files to the website, even just to change their avatar, can be a significant security risk. There is a risk that the uploaded file, no matter how harmless it may look, may contain a script that, when to run on the server, will open the website perfectly.
