For organizations and businesses worldwide, cybersecurity has become a top priority because of the frequent cyberattacks. With technological advancement, these attacks have become more sophisticated hence, companies are investing in antivirus software, threat detection systems and firewalls.
However, I feel it is not always effective because as recent history suggests, cybercriminals are exploiting misconfigurations and human errors. Brute force hacking attempts are quite old school and are quite out of trend.
Let me tell you, there are several reasons which might create an entry point for cyberattackers such as software updates, single oversight employee awareness or a gap in access management. The attackers can easily infiltrate the network of the organization through any one of these gaps.
Common Cybersecurity Mistakes
You will be shocked to know that most of the cyberattacks have been due to simple mistakes or overlooking data management. Several reasons for overlooking such as unpatched vulnerabilities and weak password policies have led to data breaches, financial losses and ransomware attacks.
There have been times when businesses have faced significant damage to realize they have been compromised. It is due to this tendency of having severe financial loss, integrity and data losses, that you need to learn more about cybersecurity mistakes.
It is important for you to understand the common mistakes so that you can strengthen your business, its defences and reduce the risk of a security breach. The most critical area to focus is improper access control as it creates an opening for unauthorized users as the network is left open.
Attackers do take advantage of authentication weaknesses! This is the outcome of misfigured delegation privileges; however, a system is unable to detect this until major damage has already been done.
Blotchy Access Control and Misconfigurations of Delegation Privileges
One of the most common mistakes is the way access control measures are taken. A lot of organizations are unable to manage the access control because it cannot be implemented effectively. Vendors and employees might need access privileges at times for several applications however, security gaps still.
Authentication mechanisms are often targeted by cybercriminals to gain entry into a system without authority. Additionally, the delegation settings are often misused by cybercriminals and they keep looking for security gaps which they can exploit.
The unconstrained delegation in Active Directory is a misfiguration that might put your organization at risk. Obviously, every system grants excessive delegation privileges to a lot of vendors and employees. The privileges allow users to impersonate other users, even at times administrators.
If the unconstrained delegation is enabled and the attacker gains control of a compromised machine, there is a high probability that they will escalate the situation. They have the power to steal authentication tokens along with using the access control to evaluate the network and move it laterally.
Sensitive information and sensitive systems are hacked with the help of access management control and they would not need any additional credentials as such.
What should an Organization Do?
If you are a member of an organization, to prevent any kind of risks related to cyberattacks, you need to restrict delegation settings. Furthermore, you also need to regularly audit your systems and access control ensuring that all systems can be trusted.
It is your responsibility to implement proper access controls along with monitoring all authentication requests and enforcing the principle of least privilege. These implementations will help you to minimize any risk of an attacker using this to leverage any vulnerability in the system.
Furthermore, the network of an organization should not have any vulnerability that is easily accessible to cyberattackers. This is the rule of how to not make cybersecurity mistakes in the future.
Software Updates Neglect and Patch Management
If you have unpatched systems and your software is outdated, you have created a perfect way of allowing cybercriminals to invade the IT infrastructure of the organization. Known vulnerabilities are often targeted for a lot of cybercriminals in security tools, applications and operating systems.
One of the easiest ways for them to know that your IT system is vulnerable is if your software is not updated. As a business, you have to update software regularly so that you do not leave yourself completely exposed to threats. You can easily prevent any such threat with a simple patch thus, creating a secure network.
When organizations neglect critical security updates, you will fall victim to high profile cyberattacks such as WannaCry attack. These attacks easily spread across the network in the organization hence, it is a better option when a business is targeted.
Automated tools are often the resources used by Hackers who scan the software and learn whether they are outdated or updated. If you are a business, you need to rapidly resolve the patching process or you are sitting ducks for cyberattacks.
In my opinion, there should be a structured patch management process which will ensure that all softwares is updated. This means, all third party applications are also regularly updated leading to minimalistic attack risks.
Furthermore, you can also use vulnerability scanners along with automated update tools which will help you detect application of patches along with detecting outdated systems regularly. This way, you can keep your system updated in a timely manner.
Poor Password Policies and Weak Authentication Practices
One of the leading causes for security breaches is still weak passwords even with repeated warnings. Every cybersecurity professional keeps warning us to create passwords stronger and yet, organizations are falling prey to it.
There are still employees in your organizations that are still using very simple passwords that keep opening for cyberattacks. Even the credentials are reused across several accounts or even fail to regularly update passwords.
Henceforth, these credential-stuffing attacks and brute-force techniques are used by attacks to exploit the weaknesses. Finally, critical systems are evaluated to check whether they can be invaded with simple security mistakes. Organizations make this mistake especially when they lack that initiative!
Lack of Employee Security Training
Another significant reason why organizations consistently make cybersecurity mistakes is because there are human errors. With all the advanced security tools implemented, the concern with human error still does not seem to be resolved.
The employees are the first line of defense in any organization especially when it comes to password management, access management control, network integration and others. Cyber threats and attacks are easier when employees keep making mistakes.
Of course we cannot completely blame them if organizations do not train them well. It is important for employees to recognize any and all security threats and avoid them, however, for that they need proper training.
When does cybercriminals tricks employees into doing something that will easily make the organization vulnerable to cyber threats. Phishing attacks are what we call when you as an employee you might click on malicious links or reveal sensitive information.
There are fake login pages, social engineering tactics and emails used by attackers to deceive employees. As users, employees easily download malware or hand over credentials with the phishing attacks. It is the responsibility of an organization to train employees to recognize the phishing attempts!
They learn how to avoid suspicious links as well as follow some of the best practices so that as an employee you can handle sensitive data. Conducting simulated phishing exercises, companies will help employees identify the gaps, reinforce cybersecurity and become aware while handling daily operations.
Overlooking Insider Threats
Apart from the external risks of hacking and threat, there are also significant issues of insider threats. It is equally dangerous as your employees, business partners and contractors have access to sensitive data.
Whether intentionally or unintentionally, there are security risks from inside too. There are several forms in which insiders can risk the security of your organizations.
Insider threats can take many forms, including:
- Malicious insiders – Individuals who intentionally leak, steal, or sabotage company data.
- Negligent insiders – Employees who accidentally expose sensitive data due to careless behavior, such as using weak passwords or falling for phishing scams.
To mitigate insider threats, organizations should implement strict access controls, conduct background checks on employees with high-level privileges, and monitor user activity for suspicious behavior. Security awareness programs can also help reduce the risk of unintentional data breaches caused by negligence.
Failing to Secure Third-Party Integrations and Supply Chains
Many businesses rely on third-party vendors, cloud services, and software integrations. But these connections can pose security risks if not managed properly. Cybercriminals often exploit vendors to access larger organizations, as seen in the 2020 SolarWinds attack.
To reduce risks, companies should assess vendor security, enforce compliance with industry standards, and limit third-party access. Regular audits and monitoring help detect vulnerabilities before they become major threats.
Poor Network Segmentation and Lack of Endpoint Security
Many organizations fail to properly segment their networks, allowing attackers unrestricted access once they breach a system. Without network segmentation, a single compromised device can expose the entire infrastructure to cyber threats.
Endpoint security is another often overlooked area. Laptops, mobile devices, and Internet of Things (IoT) devices connected to corporate networks create additional entry points for attackers. If these endpoints are not secured, cybercriminals can use them as gateways to infiltrate an organization’s network.
To strengthen security, organizations should:
- Implement network segmentation to restrict access to critical systems.
- Deploy endpoint protection tools that monitor and secure devices.
- Enforce security policies for remote workers and bring-your-own-device (BYOD) environments.
Cybersecurity mistakes are often the root cause of major breaches. From misconfigured access controls and unpatched systems to weak passwords and insider threats, organizations must take a proactive approach to security.
Implementing strong access controls, enforcing security policies, and conducting regular employee training can significantly reduce risks. Businesses must also stay up to date with emerging threats. Regularly update their software, and secure third-party integrations to prevent supply chain attacks. A proactive and security-conscious approach ensures that businesses remain resilient in an increasingly digital world.
