It is vital to be prepared and be able to detect cyber and IT security threats to your organization before any data gets stolen, or your computer crashes. Today we list the most common threats to your company's network and infrstrucutre security. With this knowledge, you'd be aware of what you're up against and the extent of the damage these threats could do should they succeed.

User Threats

Spear Phishing

The success of this attack is entirely dependent on an end user clicking on a link embedded in a crafty email. Unfortunately, factoring in the unlimited nature of human creativity and Social Engineering and you increase the odds of at least one target in a phishing attack clicking on a link that compromises your data.

Be very vigilant and aware. This email will seem like they've known you and have been doing business with your organization for a while so you will click on a link or an attachment.

Successful phishing attacks can bypass your defenses and one or all of the following may occur:

  • Data Theft. Once the perimeter has been compromised, cyber criminals will target confidential data, including employee, financial, and customer records. 

  • Stolen Credentials. This attemot to acquire credentials leads to them accessing targeted database or files that are only accessible by registered users in your organization.

  • Sabotage. Political extremists or rogue malware may have a more malicious intent to cause damage or disruption to your business. 

Privilged Accounts

A common precursor to many security attacks is stealing credentials and escalation of permissions. Having access to these accounts with administrative or executive priveleges gives them the key to valuable data contained in file shares or databases.

Most security threats usually target these privleged accounts to gain valuable organizational data and be rogue malicious insiders.

Application Threats

Web Application: CSS

There's a lot of web applications that contain vulnerabilities which allow attackers to use Cross Site Scripting (CSS) to misrepresent a website. This leads to these attackers getting victims to click on a malicious script or to capture their login credentials, thinking that these are legitimate websites. 

SQL Injection

SQL Injection has been one of the most common application layer attack techniques for more than a decade now. What it does it it takes advantage of public facing applications that respond to user-supplied data. It inserts customized quesries so attackers can bypass security measures and cause the applications to take on malicious actions.

This type of IT security attack usually targets web applications. Its intent is data loss as it goes after intellectual property, financial records, and customer lists. This leads to an even worse outcome - damaged reputation. Public notification of lost records is required in most cases and this negative press can of course directly impact business performance. 

Infrastructure Threats 

Botnets 

Most of us won't be aware, and probably will never will be, of our unwilling participation to botnet army. This is because, the effects on an individual system is usually minimal. A signle botnetcan be harmless. But when hundreds of these unobtrosive bots are instructed to forward transmissions to a single web application all at the same time, they can represent a serious security threat.

DDOS

This attack is one of the worst things that could happen to any online service or website. DDOS is able to incapacitate them by overwhelming them with activity from hundreds or thousands of computers participating in a botnet.

This attack can easily result in poor performance of your website as these botnets can utilize significant amounts of network bandwidth and syste, resources. And of course, this means lost productivity as existing initiatives and projects are often placed on hold when it becomes necessary to address a botnet secutiy breach.
