Securing your website is essential to keeping it safe from hackers, malware, and other external threats. There are a number of ways that you can actively secure your site, including using a web application firewall (WAF), network firewalls, antivirus software for the server(s), and maintaining up-to-date software versions.
In this article, we’ll explain some of the most common security threats against websites and how you can protect your site from them. Some of the key threats affecting website security are:
Malware and viruses
Malware is any type of software that interferes with the normal operation of a computer system, website, or network. Viruses are particular types of malware that can self-replicate and spread from one infected computer to another. Viruses and other forms of malware can cause damage to your site by deleting files, corrupting data, or redirecting visitors to different pages without their permission. A good antivirus program for your server(s) will help prevent these issues from occurring.
This type of attack targets websites that use databases for storing information about users, products, and other content. Hackers can exploit vulnerabilities in web applications’ database queries to execute malicious code on the server. This can allow them to access sensitive information and take control of the database.
Cross-site Scripting (XSS)
This attack is designed to exploit vulnerabilities in web applications that allow attackers to inject malicious content into a website’s code. Hackers can do this by using an application’s existing features to run scripts on users’ browsers, which will often contain security flaws or weaknesses. Once injected, these scripts have the potential to hijack user accounts and acquire sensitive data from visitors.
Denial-of-Service (DoS) attacks
DoS attacks are used by hackers to overwhelm websites with large amounts of traffic in order to take them offline. These types of attacks commonly target sites that generate high volumes of traffic and make money through advertising, or that depend on online sales.
How can I improve website security?
One of the best ways to protect your website is to use a web application firewall (WAF) and network firewalls. A WAF sits between your website and the internet, blocking malicious traffic before it reaches your site. Meanwhile, network firewalls help you prevent attacks by monitoring traffic inbound and outbound from within an internal network.
In addition to using these types of measures, you should also keep all critical software applications up to date with current versions and patches. This includes both the underlying operating system for your server(s), as well as any content management system (CMS) or ecommerce platform that you use.
Additionally, you should take steps to secure your login credentials and ensure that only authorized users have access to the website’s administrator accounts. For larger sites with hundreds or thousands of employees, implementing role-based authentication can help limit access rights based on an individual’s role within the organization.
You should also make sure that all passwords for your site are strong and difficult for attackers to guess. You can use NIST guidelines for creating strong passwords as a starting point. Finally, carefully review all third-party plugins and extensions that you install on your site. These often contain security vulnerabilities that hackers can exploit if they are not properly maintained.
In addition to taking proactive measures like those mentioned above, it is to regularly monitor your site for any warning signs of a security breach. This includes checking server logs to see if there are any suspicious network requests and analyzing web analytics data to look for unusual spikes in traffic.
What should I do if my website is breached?
If you suspect that your site has been hacked, it is important to take immediate action by isolating the affected areas and restoring them from backup files. If you do not have backups, then you must contact the hosting provider or service that runs the server where your website lives. The provider will likely be responsible for reinstalling all of the software on the system and deleting all of the malicious code that was injected onto your site during an attack. Once this process is complete, they can restore a clean copy of your site.
If you are using a WAF or other security service, it is also important to contact their support team immediately and provide them with details about the attacks that were launched against your site. This will enable them to determine if the attack came from inside or outside of the network. Once this information has been collected, you can typically receive an assessment from the provider within 1-2 hours after reporting a breach.
The speed at which you can resolve threats depends on how secure your infrastructure already is. For example, some providers offer fixes for different types of exploits in seconds through dynamic patching services, while others may take longer due to more complex implementations of protections. Regardless of how quickly an incident response team responds to your breach, however, it is always important to act quickly and when necessary, involve the authorities in the investigation.
What are the consequences of a security breach?
One of the biggest dangers posed by website hacks is their potential to contaminate other machines on your network or even across your entire organization. This type of infection usually happens through email links, bogus downloads, or phishing attacks where users inadvertently grant access rights to an attacker, who then has control over that computer and can install malicious code or steal sensitive information from it.
If this process spreads throughout your systems, you could end up losing thousands, if not millions, of dollars due to downtime while addressing these infections as well as any damages that result from stolen data. In addition, once the security breach is made public, it can take a major toll on your company’s reputation as well.
While there will always be external forces trying to infiltrate and compromise websites, taking proactive measures that prevent these attacks from succeeding can minimize the damage and ensure that business operations are not interrupted. With more time, money, and resources dedicated to website security in recent years, many organizations have been able to achieve this objective with minimal effort thanks to automated solutions for blocking threats or mitigating their effects. However, until the entire internet community shifts toward greater website protection strategies such as SSL certificates and HTTPS encryption protocols – all network operators need to work together to reduce the likelihood of successful hacks over time.
