What Are Cybersecurity Threats
When a business closes for the day the doors are locked and the alarm turned on with security cameras. The physical security of an organization is just as important as the cybersecurity of an organization as criminals look for any unsecured part of a company’s network and infrastructure to attack and often those attacks go unnoticed for months.
What Are the Top Cybersecurity Threats
There have been many large ransomware attacks in the United States in the past year and continue to be a serious threat for all organizations. Attackers continuously look for new vectors to avoid detection from information security teams. Unpatched systems are an easy method to find ways in a company’s network and computer systems. The news reports the attacks and often the millions of dollars requested in cryptocurrency to provide the key to decrypt the systems. The impact on the loss of business due to a ransomware attack is often not something that a business can recover from and continue to meet business needs.
The pandemic caused a change in the methods that were used to create secure environments for many companies when workers primarily worked from their own homes connecting to networks that security levels were unknown. Many workers have no understanding of the cybersecurity threats associated with connecting to a home network that has default administrative passwords. Connecting a business asset to a personal network increased the attack surface that was available exponentially.
Denial of Service
Brute-force attacks intended to overwhelm a system and cause networks to fail due to a large amount of traffic have increased over the past year. As technology improves the attackers gain additional resources to create botnet networks or swarms that can easily overwhelm an entire enterprise network from causing no connectivity to slow response times. An increased threat on SNMP exploits has caused new concerns as the firewalls that have been implemented are bypassed and the enterprise network of servers, printers, switches, and modems are easily compromised.
Attackers are using malware on systems and avoiding detection through the use of system tools that already exist on the system and are not known malicious attack vectors. Malware is often detected through the delivery method of file attachment or the creation of new files except attackers have bypassed that using file-less attacks and common system tools.
Phishing attacks continue to be a threat as users can be tricked into clicking links and visiting malicious sites that appear to look legitimate. People continuously look for information to understand ongoing events or trust emails are filtered through the company’s security systems. Work from home has increased the vulnerability of users as more emails are being sent.
