06 Oct Data Security and Protection
What Is A Data Breach?Put simply, a data breach is any illegal intrusion or access to private data. Such data may be financial information, patient health information, social media content and more. In any instance, confidential and potentially sensitive information is accessed without proper authorisation. Breaches are usually the result of cyber-attacks such as ransomware, phishing, and similar tactics. Any level of a data breach can result in a massive financial and reputational loss for the targeted organisation. If the latest statistics are anything to go by, then more than 3.2 million records were compromised in the top ten data breaches of 2020 to date. This really hits home the massive prevalence of data compromise in the 21st century.

The Importance of Data SecurityThe above figures themselves are evidence enough that data breaches are a clear and present threat to information, specifically financially relevant information. As a result, businesses everywhere are putting more and more emphasis on data security every day. Without going into cryptic jargon, it suffices to say that data security is the use of principles, practices, and measures to safeguard digital (and even non-digital) data. Data security measures aim to protect against data compromise and work to detect and remediate any security breaches. Using proper data security principles, organisations can ensure the safety and authenticity of their data stores. Apart from businesses, data security is of immense importance to individuals as well. In the digital world, we live in, aspects of our lives are available as digital data. Any corruption, steal, or loss of such data can wreak havoc on us personally. As a result, it is important to maintain proper digital practices to mitigate the risk of compromised data. The following are some of the many reasons why enhanced focus on data security and protection is essential in 2020 and beyond:
- Data breaches can negatively affect business reputation
- They can result in loss of sensitive and business-critical information
- Loss of customer data can harm revenues, affecting the bottom line
- They can invite inspection from compliance authorities and even penalties
- Data breaches can invite the need to reinvest and reinvent the entire IT system of an organisation
- They can result in personal losses such as identity theft
Securing data against breachesPrevention is always better than cure, and it is best if businesses take the proactive route to data protection. There are many methods to secure data. Some of them are as below.
Disk Level EncryptionThis method involves encrypting or scrambling the data stored on disk so that it cannot be read by anyone except the authorised person(s). Encryption is a mathematical concept that applies complex conversions to ensure data protection. This can be achieved through software as well as hardware means and can be a good line of defense against a security breach.
FirewallsA firewall is any hardware and/or software-based barrier that screens all data going in and out of an organisation’s internal network. A strong firewall can help to prevent unauthorised access and protect data against breaches. Firewall is the crucial element for any organisation as on the outbound side, it is used to prevent employees from sending certain types of emails or transmitting sensitive data outside of the network. On the inbound side, they can be programmed to restrict access to certain websites (like social networking sites).
Regular BackupsThis is one of the tried-and-tested methods of data protection. Keeping multiple copies of your data can help to retain access to the information and continue operations, even when there is a breach in one data store. Backups are a clean solution that can help you retrieve lost information in the case of a data compromise. It is also a safeguarding measure in the event of ransomware attacks.
Strong Access Rules
Often, in an organisation, careless practices such as weak passwords and lack of regular updates can compromise systems. Therefore, it is essential that there exists a strong security policy governing data access. Strong passwords, regular access logging and proper physical barriers to access can all help establish a culture of security.All the above practices, combined with others, can help ensure solid data protection and a compliant environment.
