Cyberterrorism

 

Cyberterrorism is any premeditated, politically motivated attack against information systems, programs and data that results in violence.

The details of cyberterrorism and the parties involved are viewed differently by various organizations. The U.S. Federal Bureau of Investigation (FBI) defines cyberterrorism as any "premeditated, politically motivated attack against information, computer systems, computer programs and data which results in violence against noncombatant targets by subnational groups or clandestine agents."

Unlike a nuisance virus or computer attack that results in a denial of service (DoS), the FBI distinguishes a cyberterrorist attack as a type of cybercrime explicitly designed to cause physical harm. However, there is no current consensus between various governments and the information security community on what qualifies as an act of cyberterrorism.

Other organizations and experts suggest that less harmful attacks can also be considered to be acts of cyberterrorism, as long as the attacks are intended to be disruptive or to further the attackers' political stance. In some cases, the differentiation between cyberterrorism attacks and more ordinary cybercrime activity lies in the intention: The primary motivation for cyberterrorism attacks is to disrupt or harm the victims, even if the attacks do not result in physical harm or cause extreme financial harm.

In other cases, the differentiation is tied to the outcome of a cyber-attack; many cybersecurity experts believe an incident should be considered cyberterrorism if it results in physical harm or loss of life, either directly or indirectly through damage or disruption to critical infrastructure. However, others believe physical harm is not a prerequisite for classifying a cyber-attack as a terrorist event. The North Atlantic Treaty Organization, for example, has defined cyberterrorism as "a cyber-attack using or exploiting computer or communication networks to cause sufficient destruction or disruption to generate fear or to intimidate a society into an ideological goal."

According to the U.S. Commission on Critical Infrastructure Protection, possible cyberterrorist targets include the banking industry, military installations, power plants, air traffic control centers and water systems.

Methods used for cyberterrorism

The intention of cyberterrorist groups is to cause mass chaos, disrupt critical infrastructure, support political activism or hacktivism, and inflict physical damage or even loss of life. Cyberterrorism actors use a variety of attack methods. These include but are not limited to the following:

  • Advanced persistent threat (APT) attacks use sophisticated and concentrated penetration methods to gain network access and stay there undetected for a period of time with the intention of stealing data. Typical targets for APT attacks are organizations with high-value information, such as national defense, manufacturing and the financial industry.
  • Computer viruses, worms and malware target information technology (IT) control systems and can affect utilities, transportation systems, power grids, critical infrastructure and military systems, creating instability.
  • DoS attacks are intended to prevent legitimate users from accessing targeted computer systems, devices or other computer network resources and can be aimed at critical infrastructure and governments.
  • Hacking, or gaining unauthorized access, seeks to steal critical data from institutions, governments and businesses.
  • Ransomware, a type of malware, holds data or information systems hostage until the victim pays the ransom.
  • Phishing attacks attempt to collect information through a target's email, using that information to access systems or steal the victim's identity.

Defending against cyberterrorism

The key to countering the threat of cyberterrorism is to implement extensive cybersecurity measures and vigilance.

On the corporate level, businesses must ensure that all internets of things devices are properly secured and inaccessible via public networks. To protect against ransomware and similar types of attacks, organizations must regularly backup systems; utilize firewalls, antivirus software and antimalware; and implement continuous monitoring techniques.

Companies must also develop IT security policies to protect business data. This includes limiting access to sensitive data and enforcing strict password and authentication procedures, like two-factor authentication or multifactor authentication.

Ghosting

Ghosting is to cease communications without notification. The use of the word "ghost" as a verb originated in social media in reference to dating, but the term is now used by employers to describe employees and potential employees who suddenly disappear. Typically, ghosting is used to describe: Job candidates who suddenly stop responding to messages. New hires who fail to show up for their first day of work. Employees who do not show up for a shift. Employees who leave work in the middle of the day and never come back. Some analysts blame ghosting on millennial entitlement. The reasoning is that members of the millennial generation have been brought up to feel they are special -- so special, in fact, that they do not need to follow conventional rules of behavior. Other analysts, however, maintain that ghosting behavior stems from changes in the job market and the phenomenon is simply a reflection of the laws of supply and demand in a healthy jo...

Data deduplication

Data deduplication -- often called intelligent compression or single-instance storage -- is a process that eliminates redundant copies of data and reduces storage overhead. Data deduplication techniques ensure that only one unique instance of data is retained on storage media, such as disk, flash or tape. Redundant data blocks are replaced with a pointer to the unique data copy. In that way, data deduplication closely aligns with incremental backup, which copies only the data that has changed since the previous backup. For example, a typical email system might contain 100 instances of the same 1 megabyte (MB) file attachment. If the email platform is backed up or archived, all 100 instances are saved, requiring 100 MB of storage space. With data deduplication, only one instance of the attachment is stored; each subsequent instance is referenced back to the one saved copy. In this example, a 100 MB storage demand drops to 1 MB.

A Graphics Processing Unit (GPU)

A graphics processing unit (GPU) is a computer chip that performs rapid mathematical calculations, primarily for the purpose of rendering images. A GPU may be found integrated with a central processing unit (CPU) on the same circuit, on a graphics card or in the motherboard of a personal computer or server. In the early days of computing, the CPU performed these calculations. As more graphics-intensive applications such as AutoCAD were developed; however, their demands put strain on the CPU and degraded performance. GPUs came about as a way to offload those tasks from CPUs, freeing up their processing power. NVIDIA, AMD, Intel and ARM are some of the major players in the GPU market. GPU vs. CPU A graphics processing unit is able to render images more quickly than a central processing unit because of its parallel processing architecture, which allows it to perform multiple calculations at the same time. A single CPU does not have this capability, although multi...
