Akitsukunese Information Defence Force

The Imperial Information Self-Defence Force (IISDF) is the Akitsukunese organisation responsible for preventing, defending against and carrying out. The IISDF is the youngest of Akitsukuni's three main intelligence and agencies and was created in 2005 following the forced shutdown of the Tōsandō Shinkansen. Since its foundation the IISDF has defended against numerous cyber attacks by foreign parties, and has also carried out a number of clandestine cyber attacks against targets around the globe. Despite its activities taking place mostly on the internet, the IISDF also operates at least one armed special forces group for ground control.

IISDF is headquartered in the Ryoko Asakura Cyber Warfare and Research Centre in Nagano. The Commander of the IISDF is the former Imperial Navy Admiral Toshiro Otomo.

History
In June 2005, the Tōsandō Shinkansen Disaster occurred, where unknown hackers carried out a denial attack on the Tōsandō Shinkansen computer systems. The Imperial Army's cyber defence unit was unable to prevent the attack, and a special government inquiry was launched to find the cause and create a new dedicated force to combat such threats. On the 18th of September, Emperor Shimazu formally inaugurated the creation of the IISDF.

Since then, the IISDF has blocked at least 670 major cyber attacks on Akitsukunese infrastructure, as well as numerous minor ones. They have also carried out offensive cyber operations against insurgent groups such as the JLF.

Defence against cyber attacks
The primary stated role of the IISDF is to protect Akitsukunese systems, including government, infrastructure and military systems from cyber attacks from both foreign and internal perpetrators. The Akitsukunese internet system is protection firstly through, and sensitive systems are wholly separate from the global internet. A complex system of, and  are in place to ensure attacks cannot take place, while a constantly-updated database of known attack patterns and viruses is maintained to aid  capabilities. As viruses evolve, the IISDF continuously changes its own programs and the national systems to be.

Offensive cyber attacks
Once Akitsukuni is engaged through cyberwarfare and this attack is deemed a national security threat, the IISDF can be authorised by the Prime Minister to carry out retaliatory offensive cyber attacks on targets, both domestic or foreign. Though the full extent of the IISDF's offensive capability is unknown, the IISDF is allegedly able to sabotage foreign systems with denial of service attacks, as well as the deployment of intrusive viruses.

According to anonymous sources, the IISDF also has the capability to carry out cyber espionage and has supposedly been doing so for some time. Jeongmi has blocked numerous unknown espionage attempts that are allegedly highly similar to Akitsukunese cyber warfare patterns.

Physical intervention
The IISDF also operates an armed group known as the Information Self-Defence Force Direct Intervention Group (ChoKa). This is a quick-response paramilitary unit intended to physically remove or apprehend cyber attackers or destroy cyber warfare infrastructure if necessary. Since its inception, the ChoKa has been deployed on numerous missions throughout the New Territories to combat insurgent forces' network capabilities. It is not known to have overseas deployment capabilities, but speculation has arisen that the ChoKa is responsible for the destruction of network equipment in some foreign states.
