We are in a time where businesses are more digitally advanced than ever, and as technology improves, organizations’ security postures must be enhanced as well. Failure to do so could result in a costly data breach, as we’ve seen happen with many businesses. Threat actors are going after any type of organization, so in order to protect your business’s data, money and reputation, it is critical that you invest in an advanced security system. But before you can start developing a security program for your organization, it’s critical that you understand the different types of security and how they all work together.

Information Security – Information security (also known as InfoSec) ensures that both physical and digital data is protected from unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction. Information security differs from cybersecurity in that InfoSec aims to keep data in any form secure, whereas cybersecurity protects only digital data. If your business is starting to develop a security program, information security is where you should first begin, as it is the foundation for data security. So if you are an information security specialist, your concern is for the confidentiality, integrity, and availability of your data. (This is often referred to as the “CIA.”) Most modern business data resides electronically on servers, desktops, laptops, or somewhere on the internet—but a decade ago, before all confidential information migrated online, it was sitting in a filing cabinet. And some confidential information still is! InfoSec is concerned with making sure data in any form is kept secure and is a bit more broad than cybersecurity. So, someone could likely be an information security expert without being a cybersecurity expert.

Cyber Security – Cybersecurity, a subset of information security, is the practice of defending your organization’s networks, computers and data from unauthorized digital access, attack or damage by implementing various processes, technologies and practices. With the countless sophisticated threat actors targeting all types of organizations, it is critical that your IT infrastructure is secured at all times to prevent a full-scale attack on your network and risk exposing your company’ data and reputation. Cyber security is a broad practice, demanding mastery of a number of unique skills in computational theory and practice from its most effective practitioners. Ensuring that servers, intranets, and channels built for data transfer remain protected and accessible to only those permitted, for example, falls under the realm of “information security”. While some cyber security professionals may specialize in this area, this is only one of the many dimensions of the field. Information security can be simply defined as “the protection of information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction in order to provide confidentiality, integrity, and availability.” Any point of data storage and transfer is considered to be an “information system”, which means this practice can apply to a wide variety of different environments, including those outside cyberspace. In short, Cybersecurity is all about protecting data that is found in electronic form. Part of that is identifying what the critical data is, where it resides, and the technology you have to implement in order to protect it.

When cyber-threat actors target your organization, they research not only your business, but your employees as well. They know that employees outside of IT security aren’t as aware of cyber threats, so they execute cyberattacks that exploit human vulnerabilities. Through the process of social engineering, threat actors manipulate people into giving the access to sensitive information. The most common social engineering attacks include:

  • Phishing: usually in the form of emails or chats, where the threat actors pose as a real organization to obtain personal information
  • Pretexting: when a threat actor impersonates an authority figure or someone that the target would easily trust in order to get their personal information
  • Baiting: when threat actors leave a malware-infected device, such as a USB or CD, in a place where it can be easily found by someone, who would then use the infected device on their computer and accidentally install the malware, giving the threat actors access into the target’s system
  • Quid pro quo: when a threat actor requests personal information in exchange for some form of reward, i.e. money, free gift or a free service

Network Security – Network security, a subset of cybersecurity, aims to protect any data that is being sent through devices in your network to ensure that the information is not changed or intercepted. The role of network security is to protect the organization’s IT infrastructure from all types of cyber threats including:

  • Viruses, worms and Trojan horses
  • Zero-day attacks
  • Hacker attacks
  • Denial of service attacks
  • Spyware and adware

There are many components to a network security system that work together to improve your security posture. The most common network security components include:

  • Firewalls
  • Anti-virus software
  • Intrusion detection and prevention systems (IDS/IPS)
  • Virtual private networks (VPN)
