Unmasking a Digital Threat: Computer Vulnerabilities in the modern age

July 17, 2023

Although the internet is a useful and fascinating place, it can also be highly dangerous for our information, digital assets, and even hardware. This is due to the existence of computer vulnerabilities, weaknesses in software or equipment that can be exploited by hackers. These vulnerabilities have been around for over 30 years, but they have become more dangerous today and hackers have more resources available to exploit them.

Therefore, let's discuss the most common dangers that threaten an organization's digital assets and how to stay safe from them. Furthermore, if you want to be prepared to combat these threats, remember that at ES Consulting, you will find the best consultancy services.

Current Computer Vulnerabilities and Threats

The threats that complicate our journey through the digital world are a direct result of the presence of computer vulnerabilities. As mentioned before, vulnerabilities are weaknesses in any system that, when exploited, allow unauthorized access that jeopardizes the integrity of software and its information. In the early days of the web and computing, vulnerabilities were numerous, but the threats did not have the effectiveness they have today. While there were some famous cases of money losses due to computer viruses in the 1990s, it doesn't compare to the number of incidents we have today.

This primarily occurs because a significant part of our lives and the lives of organizations revolves around the digital world. This means that hackers have many more potential victims available, and they have managed to diversify their methods. Detecting vulnerabilities and exploiting them is their specialty, this why efforts and investments in computer security must be doubled. But what types of vulnerabilities exist, and how are they detected?

Types of Digital Vulnerabilities and How They Are Exploited

The number of vulnerabilities that can exist in the digital world is incalculable because there is a universe of them yet to be discovered. This means that organizations and users in general need to have a basic understanding of best practices to avoid creating security breaches that jeopardize the integrity of the computer environment.

Therefore, it is worth knowing the most common types of vulnerabilities at present and how hackers approach them.

Design Vulnerabilities

In the realm of networks, we deal with network protocols such as TCP/IP, for example. These protocols have been improved and updated over the years because their initial designs had vulnerabilities that would be very dangerous today. Similarly, when security policies are created for network environments, design errors can occur.

They are named design vulnerabilities because they persist from the design stage, that is, from when the protocol or security policy is conceived on paper. This implies a drastic change in the way their operations are planned while maintaining their intended function.

Manufacturers usually address this type of vulnerability, and if not, it may involve switching to a similar alternative.

Implementation Vulnerabilities

These vulnerabilities arise from software developers or the people responsible for implementing programs or the infrastructure where software will reside. Leaving backdoors, test users with privileges or open access that should be restricted are part of this category.

If a hacker becomes aware of the presence of these elements or detects them, they can exploit them within a few hours. Avoiding these threats is a matter of the professionals involved adhering to best practices.

Maintenance Vulnerabilities

All elements involved in a computer system, from hardware to software, need to undergo regular maintenance processes. Maintenance not only involves external or internal cleaning of equipment or programs but also their periodic updating.

Updating the organization's software or your personal computer is essential for keeping threats at bay. This is because each update corrects vulnerabilities from the previous version, keeping us one step ahead of hackers by closing the gaps they had available.

User Vulnerabilities

Users are generally the weakest link in the chain and one of the main targets for hackers to exploit. User vulnerabilities occur due to lack of knowledge and can be exploited through various methods, such as phishing emails, fake links, weak passwords, and social engineering techniques.

However, this is something that has been gradually mitigated in recent years through training programs that promote good practices in companies. Users with basic knowledge in this area are capable of keeping their computers secure and thereby protecting the network of the organization.

Best Practices to Avoid Vulnerabilities

An organization's network consists of different elements, from servers to routers, and all devices that converge on the network, such as mobile devices, printers, and computers. All of them are vulnerable to attacks, which is why IT departments must consider a set of best practices to maintain security.

Some of these practices include:

- Security policies: From the network to the servers that control resource operations, appropriate security policies must be in place. This includes user hierarchy for accessing specific areas and the presence of antivirus software and firewalls.

- Prevention methods: Having a well-structured user directory with rules for strong passwords and promoting secure communication within the network environment.

- Backup generation: Backups are crucial for security, as they allow for business continuity in the event of compromised data.

- Software updates: Applying all available updates to operating systems, applications, and programs used on the network will help reduce vulnerabilities.

- User training and awareness: Providing basic knowledge of computer security to individuals using computers and equipment makes a difference in reducing the number of vulnerabilities.

Security breaches are a significant problem in the digital world, and mitigating them requires a combination of technical elements, knowledge, and practices to keep them at bay. Paying attention to cybersecurity in your company allows you to handle any type of information with peace of mind, reducing the risks of corruption, ransomware, or data leaks.
