Defense Strategies to Combat Insider Threats

February 2, 2021

Insider threats are businesses' biggest but most overlooked cyber user risks. Companies spend a lot of money protecting their networks from outside attacks but often forget about dangers from within. Even though people are becoming more aware of this risk, over half of businesses still don’t have a plan to handle insider threats. This leaves them open to serious security problems.

The Cost and Impact of Insider Threats

It can take 280 days to find and stop a data breach caused by someone inside a company. This can cost millions, leading to data theft, financial loss, and company reputation harm. Without strong security, businesses are at risk. Core Technologies Services Inc. helps companies protect their data, detect threats early, and stop problems before they cause harm.

Insider threats can cause serious problems for businesses:

  • Huge money losses from system downtime, fixing damage, and paying fines.
  • A bad reputation makes customers lose trust.
  • Legal trouble for not keeping important data safe.
  • Business slowdowns that take months to fix.

At Core Technologies Services Inc., we know insider threats can be tricky. We provide robust IT User Solutions to detect, block, and prevent risks before they become major threats.

What Are Insider Threats?

An insider threat is when someone within a company misuses their access to harm the business.

This can happen in two ways:

  • On purpose (like stealing data or damaging systems).
  • By accident (like sharing sensitive information without realizing it).

Insider threats are hard to spot because these people already have permission to use company systems. If no one is paying attention, they could cause big problems, and no one might notice for a long time.

Categories of Insider Threats

Careless Employees (60% of cases)

These people don’t mean to cause harm, but their bad system user habits can put the company at risk. Some common mistakes include:

  • Clicking on fake emails (phishing scams) that let hackers into company systems.
  • Using weak passwords or reusing the same password for different accounts.
  • Not updating their devices with the latest security fixes.
  • Losing company laptops, phones, or USB drives, which could expose important data.

Even though they don’t do it on purpose, these mistakes can cause big problems for a business.

Malicious Insiders (23% of Cases)

A malicious insider is someone inside a company who misuses their access to harm the business. They might do this for money, revenge, or to help a competitor.

Examples of What They Do:

  • Sell private company or customer information to other businesses.
  • Delete or change important files to cause problems.
  • Break systems or software to make the company lose time and money.
  • Leaking secret information to damage the company’s reputation.

These actions can cause serious harm to a company, making it lose money, customers, and trust.

Stolen Passwords (14% of Cases)

Hackers often steal or use leaked employee passwords to break into a company’s systems, cloud services, or network. They do this in different ways, such as:

  • Phishing emails that trick employees into sharing their passwords.
  • Brute force attacks that guess weak or common passwords.
  • Buying stolen passwords from past data breaches on the dark web.

At Core Technologies Services Inc., we keep businesses safe by spotting insider threats, sending security alerts, and protecting passwords.

The Damage Caused by Insider Threats

These threats can happen because someone is careless, has bad intentions, or has their account stolen. They can lead to huge money losses, data leaks, business problems, and damage to a company's reputation.

Even one insider attack can cause serious harm. Below, we look at common risks and real-life examples of how damaging these threats can be.

Data Theft and Breaches: The Hidden Danger Within

One of the biggest risks with insider threats is employees or contractors stealing or leaking important company info. They often have access to private business data, like:

  • Customer Information – Things like your credit card numbers, Social Security info, or contact details. If stolen, this can lead to identity theft or fraud.
  • Intellectual Property (IP) – Unique ideas, inventions, or plans that make a company special and successful. Think of it as the "secret sauce" that sets them apart.
  • Financial Records – Bank details, payroll info, or company earnings. This relies on preserving the entire meaning of the sentence.

Corporate Trade Secrets – Super-secret stuff like special formulas, designs, or processes that give a company an edge. If leaked, competitors could copy them and take away that advantage.

Business Downtime and Financial Loss

A harmful insider, like an unhappy worker or someone who shouldn’t have access, can do a lot of damage. They might delete important files, turn off security systems, or mess up important equipment. An insider threat happens when someone inside a company, like an employee, misuses their access to hurt the business. This can cause serious issues like losing money, disrupting work, or even breaking the law.

  • Downtime – Employees can’t access important information, which slows down work and hurts customer service.
  • Lost Productivity – Teams waste time trying to recover lost files instead of doing their jobs.
  • Reputation Damage – Customers and partners might not trust a company that can’t keep its important information safe.

Real-World Example: A Costly Insider Attack

  • Without public backups, the company couldn't restore its data. This caused serious financial problems.
  • This highlights how one bad action can harm a business. It shows the need for strong security, regular backups, and monitoring risky behaviour.
  • To prevent such problems, companies should limit access to sensitive information. They should use extra security measures. This includes multi-factor authentication (MFA), watching for unusual activity, and ensuring safe backups. This way, the business can keep running even in the face of insider threats.

Property and Infrastructure Damage

A former Cisco employee caused a serious security breach. They had unapproved access to the company’s cloud. They deleted 456 virtual machines with intent. This harmful act caused major disruption.

Impact of the Incident

  • Financial Loss: The company spent $2.4 million on recovery. This included restoring lost data, rebuilding virtual environments, and adding stronger security measures.
  • Notable Damage: Events like this can harm customer trust. This may result in business losses and legal issues.
  • Security Weakness Exposure: This event showed weaknesses in access control and employee offboarding. It stressed the need for stricter security protocols.

Key Lessons Learned

To prevent similar incidents later, organisations should:

  • Use strict access control policies – Revoke access for former employees right after termination.
  • Continuous Security Monitoring – Detects and responds to suspicious activity before significant damage occurs.
  • Multi-Factor Authentication (MFA) – Add an extra layer of security to prevent unauthorized logins.
  • Data Backup & Recovery Plans – Keep backups current. This helps restore systems in a short time if there's deletion or a cyberattack.

This case reminds us how vital strong online safety is. It protects critical infrastructure, data, and business.

Acclaimed Harm

  • In today's digital world, one security issue can hurt a company's reputation. This can make customers lose trust.
  • When someone steals sensitive information, customers may lose trust in the company. They might choose to go to a competitor instead. This means the company could lose money and damage its image.
  • Investors and business partners may avoid companies with security issues. They might worry about future risks, fines, or money problems due to the breach.
  • Bad publicity from a security issue can hurt the company's stock prices. It may also lead to fines and even cause legal problems, making things worse.

Common User Behaviors That Increase Insider Threat Risks

There are a few things that can make a company more at risk of insider threats:

  • Too much access can be risky: If employees see or use more information than necessary, it can lead to problems.
  • Weak passwords: Choosing easy passwords or using the same one for different accounts makes it easy for bad actors to steal them.
  • Unwatched powerful users: Senior staff, like bosses, IT workers, and finance officers, have the most access.
