Data protection has become an essential part of all business strategies, no matter the company’s size. The global average cost of a data breach reached $4.24 million in 2021. The jump in cost was also associated with the impact of remote work during the pandemic.
Hackers have also evolved the way they execute cyberattacks. Nowadays, it’s easier to use phishing and social engineering attacks to infiltrate a network and spread malware and ransomware. Identity theft or tricking employees into revealing credentials, or clicking an infected link or attachment is all cybercriminals need to gain access to a work laptop. Once inside, they can easily infect the entire network.
Big companies are, in many cases, way ahead in the data protection game, having already built their security policies and tested them for the last few years. However, their requirements are also more complex. Many of them need to protect other categories of data beyond customer information, such as intellectual property and financial data. Let’s look at the most successful ways to protect data in an organization and ensure corporate data security.
1. Advanced protection against external threats
To address external security threats, big companies deploy and regularly update basic measures such as two-factor authentication, firewalls and antimalware solutions. They also go further by implementing more advanced strategies such as Trusted Platform Module (TPM) capabilities and adopting Zero Trust architecture.
Zero Trust architecture proposes a new way of tackling cybersecurity: never trust, always verify. It ensures that users, devices, and network traffic are all verified and subject to least-privilege rules when accessing trusted resources. In this way, if one computer becomes infected, attackers are prevented from moving laterally across the network.
2. Knowing where data is and where it’s going
One of the most crucial steps towards efficient data protection is knowing exactly which data is being stored and where. By accurately identifying their data lifecycle and the security risks associated with it, companies can make informed decisions concerning the measures they need to protect it.
Large organizations scan company networks for sensitive data. When finding it in unauthorized locations, they have the option of deleting or encrypting it. In the age of data protection regulations, transparency is key both for compliance and for building effective data protection policies.
3. The use of encryption across the board
From encrypted hard drives, USBs, and smartphones to data encrypted prior to its transfer to the cloud or onto portable devices, encryption has become essential to protect sensitive company data and secure customer data.
Encryption tackles two common data protection vulnerabilities in today’s global economy: a workforce constantly on the move and the rise of remote work. With devices frequently leaving the safety of company networks, encryption ensures that, in case of theft or loss, the sensitive data they contain is inaccessible to outsiders.
4. Educating employees at all levels
The human factor is often the biggest vulnerability in the data protection chain. Large corporations ensure employees are informed of compliance regulations and best security practices, providing them with both training and clear guidelines for those coming into contact with the most sensitive data types.
C-level executives are frequently targeted by malicious outsiders due to their high-level access to data. Big companies take special care that higher management does not circumvent the rules as it is essential that the same level of data security is maintained across the board, not only horizontally but also vertically.
DLP solutions can act as an effective method of enforcement by setting clear policies that protect and restrict access to sensitive data. Levels of access to data can be controlled based on groups, departments, specific users or endpoints.
5. Creating BYOD policies
As companies embrace Bring-your-own-device (BYOD) policies that increase productivity and reduce costs, they often ignore their security implications. Accessing sensitive information on personal devices means that data is travelling outside the confines of the company network, effectively rendering any security measures taken to protect it moot.
Big organizations restrict the sort of data that can be transferred outside company devices. At the same time, device control policies can be applied, which ensure that only devices that meet a certain level of security are trusted. In this way, employees are given the option of aligning the security of their personal devices to the level required within the company. If they choose not to apply them, it guarantees that no sensitive data is allowed to be transferred to them.
As we move forward into the age of data protection by design and by default, mid-sized and small businesses must follow in the footsteps of larger companies and adopt security plans to protect data from insider and outsider threats.
