Top 20 Security Threats We Fend Off to Protect Our Clients

9 min read

The online security threats of the internet are very well-known because of their vulnerabilities. You must hear of security-related news like hospital files being hacked and held ransom, credit card data being stolen from major retailers, or websites being taken offline without warning. Nobody can deny the fact that their online data and resources are at risk. In this digital era, the vulnerability of your online resources or data is very obvious. Many companies are providing the best online security tools to their clients to prevent or mitigate internet security risks. In this article, I will share with you some of the most common security threats to your data, resources, or website.

You need to choose reliable company tools to keep you protected and secure. I know you want your servers and data protected and as safe as they can be on today’s internet. To ensure the security of your servers, systems, and data, you need to recognize the security threats that can most possibly affect your resources. Here are some of the most common online security threats people complain about and there are chances that you have to deal with some of them in the future.

Broken Authentication

How many websites have some kind of authentication process? They assure you it is safe with locking images, but are they? Surprisingly (or not) there are many weaknesses in logins and session times. A failure or weakness in the authentication allows attackers to compromise passwords and session tokens as well as exploit other opportunities to gain user identity information.

Trojan Horse

A trojan horse is a spiteful bit of harmful software or code that urges users into willingly running it on the computer, by hiding itself in a legitimate program. The Trojan horse is mostly spread through email; it can appear as regular mail, and when you open the mail and it has an attachment, you can download some malware instantly to your system. It can also get into your system when you click on some fake advertisement. Once you install the trojan to your system, it will keep track of your passwords by hijacking your webcam, logging keystrokes, and stealing any confidential data from your system.

Brute Drive

Some attackers come through your security shields using brute force. It’s an attack that lacks subtlety, but it can be highly effective. With a brute drive, millions of potential login credentials are cycled through your system one after another until something works. Once they are in, they are in.

Distributed Denial Providers

Hacking strategies know no expiry dates. Distributed denial attacks may be old-fashioned, but they can still be very effective. Rather than an attack of brute force, the distributed denial attack is like a swarm of small warriors attacking in isolation all over your server. Eventually, the sheer volume of attacks consumes your bandwidth and the website is still open for visitors.


Viruses never go out of style! More than 80 percent of companies are fending off viruses via email and files daily. It doesn’t help that viruses are developing right along with the software designed to prevent them from getting through.

Viruses are bits of software that are intended to get into someone’s system without permission. They are mostly sent by a hacker through some email attachments or they can also download from malicious websites made by some hackers to infect your devices. A virus in one computer can also infect the other computer devices in a network. The viruses are also known as malicious software that inactivate your security settings, spam, corrupt, and steal data from your device including confidential data like passwords, in some cases they can also delete some information from your hard drive. Many companies offer virus protection, where you can get the best internet security antivirus.

Mass Mail Attacks

A clever attack through email, it’s no longer necessary for the victim to open an email attachment. Simply viewing the email is enough to infect your computer or server. Once infected, your server becomes a mass mail server and your business is suddenly sending waves of spam emails irritating customers and overwhelming system limitations.

Security Misconfiguration

A solid security system requires having the proper protection at every level for every application, framework, server, database, application, and platform. These should be coordinated systems and if they are not defined properly and properly maintained through updates and checks, gaps appear and the attacker can waltz right through the misconfiguration in your wall of defenses.

Security Misconfiguration


The clever hacker (and aren’t they all?) has a two-stage attack. First, he sends a nasty virus or malware your way. Resources are slammed as you deal with and do the online virus protection before the worst can happen. Then, as soon as you are relaxing at the end of the fight, the hacker walks right through the openings in your security software that you failed to close immediately after banishing the original virus.

Adware and Spyware

The “adware” is any software that is made to keep track of your browsing data, to show you the most related pop-ups and advertisements. Adware gathers information with your consent and is a genuine income source for many companies that let users install their software free of cost, and they show advertisements while using this software. The adware presence on your PC is clear on the pop-ups, and it can reduce the speed of the internet connection computer’s processor and speed. When you install some adware without using any consent, it is malevolent. The adware section is normally hidden in connected User Agreement docs, but you can see it by cautiously reading everything you receive during the software installation.

The working of spyware is quite similar to adware, but it is automatically downloaded to your system and you don’t have to install them intentionally. It also contains keyloggers that keep track of your confidential information such as credit card numbers, passwords, and email addresses, they are also proving to be a huge threat to your identity theft.

Insecure Direct Object References

Direct object references occur when a tiny hole or weakness exposes a reference to an internal implementation object like a database key or single file. Attackers manipulate the references to gain data without even triggering an alarm and a quality cyber and physical access control security systems check.

Buffer Overflows

In another series of coordinated attacks, a buffer overflow overwhelms servers with a series of assaults to lock up the system leaving defenses vulnerable to an attack.

SQL Injection

A more isolated attack, SQL injections are getting more popular with the vast treasures of personal information stored in a poorly protected database server. SQL injections wiggle right into the weak database or through a weak connection and the database information winds up in the enemy’s hands.

SQL injection attacks are made to harm your applications driven by data through misusing security weaknesses in the software application. Here, the malicious code is used to get personal data, destroy and change that data, and void website transactions. It has rapidly turned out to be one of the most hazardous confidentiality issues for data privacy. The internet is loaded with information related to SQL injection attacks as it is one of the most dangerous threats in cybersecurity issues.

Other Injection Flaws

SQL is not the only injection flaw. There are similar OS and LDAP attacks. These occur when untrusted data is sent through a command or query. The hostile data starts a chain reaction that opens the target for attacker commands and data access.


Another classic attack that is still sadly relevant, phishing is an attack through fake email. The bad guy sends an email that looks authentic. The good guy falls for it and now the bad guy has login information and any other information the good guy typed into the fake information boxes. The attacks frequently come in the form of phishing emails or instant messages made to appear authentic. The email recipient is formerly tricked into opening the malevolent link in the email, which results in malware installation on the system of the recipient. It can get your private data by sending an email, for example, a malicious email that appears like sent from a bank to confirm your identity by giving away your confidential data.

Cross Website Scripting

Hackers actively seek out weak points in your website. Once they find a likely spot, the hackers exploit that weakness to link your site to an identical website. Customers go to the identical site without realizing what is happening and enter all of their usual payment information and personal data for the hackers to collect.

Application Specific Hacking

Some hacking isn’t universal or even on a broad scale. Certain programs and applications leave holes in your armor and attackers know to look for these weaknesses to exploit them. This is especially true with automatic updates of software where new versions, complete with security flaws, may download onto your machine and create holes you’re unaware of until it’s too late.

Sensitive Data Exposure

Sensitive Data Exposure

As much as companies reassure clients, the fact of the matter is, that many websites and web applications do not have enough online internet security to properly protect sensitive data including credit cards and authentication credentials with encryption and other precautions. Attackers slip through the weaknesses in these applications to gather and use sensitive information for their purposes.

Unauthorized Access Attacks

1. Missing Function Control

Most web applications verify user-level access before allowing users into certain functionalities of the application. This process should be happening on the server with each function level access for a control check. Without failsafe verification on the server, attackers can forge requests and access functions without proper authentication.

2. Cross-Site Forgery

A targeted attack on a single user (at a time), this attack waits for a customer to log into an account before sending a forged HTTP request including session cookies and authentication information to an application. This allows the victim’s browser to send messages and requests from websites they think they can trust.

3. Malicious Forwards

Sometimes the best attacks are the simple ones. With the many forwarding websites and redirects, attackers can create their opportunity by redirecting legitimate web traffic to a new, malicious, destination page much like phishing but without the email.

4. Rootkit

The Rootkit is a software tool collection that allows administration-level access and remote control over a device or computer network. When remote access is obtained, this software can do many malicious activities as it comes with keyloggers, antivirus disablers, and password stealers.

The Rootkits hide in the legitimate software installed on your device: when they get authorization to make some modification to your operating system, the rootkit can automatically install itself on your device and wait for some hacker to start it. The rootkit software can also contain malicious links, files, phishing emails, and installing some software from doubtful sites.

5. Worms


Computer worms are malware program bits that quickly duplicate and make all the computers linked in a network. A worm spreads from an infected device by the transfer itself to all contacts of the computer, at that point, it directly gets into the contacts of other computers also. Traditional malware still has its place in the lineup. worms are easily spread not just across a website, but across entire swaths of the internet easily moving through our connections from one machine and one account to another causing billions in damages. Remarkably, the worm is not always made to cause security issues to someone; some worms are designed just to spread. The computer worm’s transmission is normally done by misusing the vulnerabilities of software.

6. Careless Consumers

Finally, the most painful attack of all – the attack of the careless customer. Sometimes you can do everything right, and have every security measure in place, and then your customer messes it all up by choosing a login that is so simple to guess, bad guys just hop right through their account into your applications and start attacking at will.

Anything online is vulnerable, and the bad guys will always be trying to get one step ahead of the good guys. What matters most is that you know the risks and you work with a company that understands the levels of security that are most important to keep your website – and your customer’s data – safe.

7. DOS & DDOS Attack

If you have ever desperately waited for some online purchase? You refresh the page again and again until your desired product goes live. When the last time you press F5, an error is shown on the page: “Service Unavailable.” This is because the servers go overloaded and cause the unavailability of service for some time.

Most of the time it happens when the server of the website is overloaded with traffic and crashes. But sometimes, it also happens to your website in case of some DoS attack or denial of service. A malevolent overload of traffic occurs when some attackers overcome websites. A DDoS attack or distributed denial-of-service attack is a more forceful attack than the DOS. It’s more difficult to overcome a DDoS attack.


In this article, I have discussed the most common security threats faced by users. This article is a good piece of information, where you can understand the reasons for some major cybersecurity threats on your website and you can also recognize them when occurred. You need to choose trustful companies’ tools or software to keep you protected and secure.
