How To Prevent Cyber-Attacks in Network Video Surveillance
In April 2014, a security bug named Heartbleed exposed millions of sensitive personal information. According to The Washington Post, network intruders could have taken advantage of the security breach during the more than two years it went undetected, tens of thousands of servers may have been exposed, and at least 500,000 servers remained vulnerable at the time of discovery.
The Heartbleed security flaw and resulting breaches prompted the US Department of Homeland Security to warn businesses and advise them to review their network security. However, despite government and private technology company responses, sensitive information was exploited, resulting in several significant cyber-attacks worldwide.
The confidentiality of about 4.5 million patients was compromised as security keys were stolen from Community Health System hospitals in the United States. In addition, the Canada Review Agency reported the theft of social security numbers belonging to 900 taxpayers.
What is a cyber-attack?
A cyber-attack is an unauthorized electronic procedure intent on disabling or destroying an internet data system to obtain sensitive personal or corporate information.
Common types of over network cyber-attacks include malware, spyware, ransomware, distributed denial of service (DDoS) attack, structured query language (SQL) injection, and phishing.
Malware is software that is intentionally developed to cause damage to computer system operations. For example, a computer virus, a Trojan Horse, spyware, and ransomware all fall under the general category of malware.
Spywares are covertly deployed to identify and extract sensitive information from personal computers or an organization’s network appliance. In addition, spywares are frequently encountered through malicious internet advertising in websites and emails.
Ransomware is designed to disable or lock sensitive information within a user or an organization’s network appliance.
Some ransomware may simply disable a system and prevent users from accessing information. Complex ransomware may disable a system, encrypt sensitive files, and prevent users or organization access unless a ransom is paid to obtain decryption keys.
A DDoS attack involves an attempt to disrupt normal network traffic of personal or an organization’s network appliance by overwhelming the targeted system with high-volume internet traffic. DDoS attacks target websites and other online services by flooding them with incoming messages, eventually bringing down servers and network appliances.
Network intruders intent on disabling or destroying data-driven applications and servers typically employ SQL injection once a breach is achieved. A malicious SQL script is inserted into an SQL data field, giving executable instructions to destroy or transfer sensitive data.
Lately, network intruders have employed phishing techniques to obtain personal information or deploy malware to an organization’s network appliance via fraudulent emails and internet messages.
Phishing emails can be sophisticated enough to simulate reputable companies and trick users into participating in what they consider normal business interactions. At the same time, network intruders breach network security and deploy cyber-attacks.
How is network video surveillance breached?
IP cameras become vulnerable to cyber-attacks due to misconfiguration, failure to change the default password, authentication bypass, and flaws in the device or software. Examples of flaws in devices or software include the Bash bug and the Heartbleed bug.
The Bash bug process command code flaw allowed a UNIX-based system’s command-line interface (Bash) to arbitrarily execute command scripts. As a result, network intruders exploited the Bash bug to gain access to network appliances through UNIX controlled systems.
In the case of the Heartbleed bug, a programming mistake in the popular OpenSSL cryptographic software library (designed to secure information over the network) allowed anyone on the internet to access the network and read the memory of systems.
Network intruders were then able to exploit this flaw and gain access to secret keys, usernames, and passwords, thereby access to servers and other network appliances.
Once a network video surveillance is breached, intruders can deploy malware into network appliances or bypass the physical security system. A network video surveillance breach can result in:
- Inefficiency and deteriorating cost-effectiveness of the network video surveillance system.
- Disability of the network video surveillance system.
- A device flaw breach that could remain undetected for a long period.
- Attackers using breached video surveillance systems and stored videos for malicious intent.
- Attackers using the breach in the video surveillance system to further attack network appliances and mainframes and obtain sensitive information.
- Attackers using breached video surveillance systems to gain physical access to a facility.
How can you “secure” your network video “security” system?
Once your network video system is exposed to a breach, its vulnerability will increase, and cost-effectiveness will decrease with continued loss. To remedy this, you will need to effectively secure your system. In addition, the solution should be easy to install, operate, and manage.
