Digital Safety First: Building a Stronger Online Defense with Cybersecurity

Table of Contents

Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users via ransomware; or interrupting normal business processes.

Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative.

What is cybersecurity all about?

A successful cybersecurity approach has multiple layers of protection spread across the computers, networks, programs, or data that one intends to keep safe. In an organization, the people, processes, and technology must all complement one another to create an effective defense from cyber attacks. A unified threat management system can automate integrations across products and accelerate key security operations functions: detection, investigation and remediation.

People

Users must understand and comply with basic data security principles like choosing strong passwords, being wary of attachments in email, and backing up data.

Processes

Organizations must have a framework for how they deal with both attempted and successful cyber attacks. One well-respected framework can guide you. It explains how you can identify attacks, protect systems, detect and respond to threats, and recover from successful attacks. 

Technology

Technology is essential to giving organizations and individuals the computer security tools needed to protect themselves from cyber attacks. Three main entities must be protected: endpoint devices like computers, smart devices, and routers; networks; and the cloud. Common technology used to protect these entities include next-generation firewalls, DNS filtering, malware protection, antivirus software, and email security solutions.

Why is cyber security important?

• The costs of cyber security breaches are rising. 
  Organisations that suffer cyber security breaches may face significant fines. There are also non-financial costs to be considered, like reputational damage.
  
  
• Cyber attacks are increasingly sophisticated.
  Cyber attacks continue to grow in sophistication, with attackers using an ever-expanding variety of tactics. These include social engineering, malware and ransomware.
  
  
• Cyber security is a critical, board-level issue.
  New regulations and reporting requirements make cyber security risk oversight a challenge. The board needs assurance from management that its cyber risk strategies will reduce the risk of attacks and limit financial and operational impacts.
  
  
• Cyber crime is a big business.
  According to a study by McAfee and the CSIS, based on data collected by Vanson Bourne, the world economy loses more than $1 trillion each year due to cybercrime. Political, ethical, and social incentives can also drive attackers.
