With the transfer of workflows to digital media as a result of the digital transformation, it is inevitable that the business world will face some cybersecurity challenges. Especially those who adopted weak cybersecurity protocols, in other words, who don't follow the principle of least privilege and zero trust become the very targets for cyber attack vectors.
The attack factor that poses the highest risk for organizations vulnerable to becoming a target and leads to high costs as a result is privilege misuse. If you don't plan well what privileges and access authorizations should be granted to which users, you can be an easy prey as well as a monetary resource for hackers.
Considering the fact that 80% of data breaches are caused by insiders, including current and former employees of companies, it is easy to understand how granting unnecessary privileges and access permissions can lead to serious issues. Besides, it's also worth mentioning that not revoking the access permissions and authorizations in time can make you vulnerable for malicious attacks, just like granting unnecessary privileges.
So, how can you prevent a cyber attacker from using the privileges on your IT network to create an attack vector?
Privilege misuse can be defined as the act of infiltrating into an IT network with the help of a privileged account to obtain data stacks of organizations, seize confidential commercial assets, steal personal data, make use of these data to make profit and attack the organizations.
On an IT network, all authenticated accounts would have standard authorizations. Users with these authorizations are standard accounts. On the other hand, privileged accounts have more authorization and access. This authorization and access system can differ depending on the hierarchical structure of and within organizations.
Credentials are also important when it comes to privileged accounts and privilege misuse. As privileged accounts are mostly connected to credentials, they can be compromised when hackers target and attack these accounts. Data Breach Investigation Report 2020 published by Verizon also reveals that the use of stolen credentials is the second most common type of data breach. The Report shows that 80% of privilege misuse breaches can be attributed to lost and stolen credentials.
Privileged users can misuse privileges in different ways. A privileged user can pose a threat to the data security principles of your IT network and access critical data stacks by performing the activities below. However, the user must have enough privileges in all situations to be able to do this.
Among these, the most commonly preferred method is account manipulation. To cause access security breaches and obtain sensitive data, a cyber attacker can perform an activity normally done by users with administrator credentials with the help of the privileged account he used to infiltrate into the system by changing the settings of the Active Directory.
Besides, attackers usually aim to run malicious softwares on systems when they use privileged accounts to perform attacks. This attempt to run malicious softwares is a serious threat against IT infrastructures and systems. It can lead to serious financial loss and damage the organization's bond with customers as it causes all workflows of the organization to come to a halt.
Below, you can find a list of methods that can be preferred by internal threats within organizations to access privileged account credentials. Internal threats usually follow these methods to access critical data.
2022 Verizon DBIR presents us remarkable data in terms of privilege misuse. 173 total incidents stand out in the report with 137 of as confirmed data breaches. Highlighting the breach incidents of 2021, the report reveals that privilege misuse with 137 confirmed breaches comes before stolen assets, which has 61 confirmed breaches. On the other hand, system intrusion as the biggest cause of privilege misuse has become the leader of 2021 with 1545 confirmed data breaches.
Additionally, the report shows that healthcare organizations are affected most by privilege misuse incidents. The healthcare sector with 29 confirmed breaches and 19% share is followed by retail with 13.7% and professional and manufacturing sectors with 13% each. While Finance has a share of 11.6%, organizations carrying out their businesses in information sector constitute 8.9% of the incidents.
To prevent privilege misuse, you should first properly identify user roles and access profiles. Then, you should manage these roles and profiles according to cybersecurity protocols of your IT network. In the mean time, you must forward the process by placing zero trust principle at the center of your security protocols of your network. And then you must build an auditable process, which consists of privileged access granting, adding and cancelling steps.
After completing the privileged access configuration of your IT network, you have three more steps to take.
To integrate these steps easily into your IT network, you can benefit from the Privileged Access Management solution, which encompasses modules such as Privileged Session Manager, Dynamic Password Controller, Two-Factor Authentication, Database Access Manager, and Dynamic Data Masking.
You can monitor privileged accounts 24/7 to build a strong control mechanism thanks to Krontech's Privileged Access Management (PAM) suite Single Connect, which has proved its success many times by getting featured in reports published by international research organizations.
Having the modules below, our PAM solution Single Connect can detect primarily privilege misuse by users with access to critical data and prevent misuse if needed.
If you wish to boost your IT network with more safety against privilege misuse with the help of Single Connect's modular structure and advanced features, you can contact our team to ask anything you want and get more information about Single Connect.
