In both the Star Army of Yamatai and a variety of other organizations (both military and civilian), computing systems have often been seen as nigh invulnerable systems tasked with not only the operation of critical systems but also tasks that are considered too mundane for trained personnel to bother. However, such a fallacy can lead to downfall as unrealistic expectations are crushed by the overbearing weight of reality.
Mostly seen in some of the more powerful organizations, “the fallacy” of invulnerable computers revolves around the use of powerful, sapient Artificial or Synthetic Intelligences with near god-like omnipotence that allows entire interstellar networks to remain unhindered by the woes of more primitive networks. Hackers and their ilk remain frustrated by the overwhelming force of security these networks are capable of maintaining. This leaves networks of these Superpowers to be overpowering and flawless beacons of Information Storing Might.
The reality is much more mundane than expected. Networks such as PANTHEON are indeed powerful, but not invulnerable. The more accurate term for it all would be resistant than invulnerable.
The artificial/synthetic intelligences involved in these “Super” Systems are what gives such networks their resistance. The main factor of their success are the speeds at which they process information accurately and efficiently. This allows faster reactions to intrusions as well as the capability of maintaining a more proactive stance on network security when compared to standard networks.
This doesn't make Information Specialists obsolete though as not even the AI / SI monitors of such a network can be completely safe. Sometimes intrusions or cyber-war implements can target these monitors, making the Information Specialist the 'hero' that rescues the 'victim'.
With networks that do not have the advantage of Artificial / Synthetic Intelligences to monitor them, the Information Specialist's importance is almost tripled. Without the constant vigilance of the Monitor, the Information Specialist must set up alarms and constantly maintain security on networks to insure confidentiality and authentication.
Computing Systems and their Networks have many weaknesses both artificial and natural. While some of these weaknesses can be compensated for and / or protected, it is impossible to completely protect from all of them.
Artificial weaknesses are exploits and design flaws that have either been purposefully added through sabotage in the design phase, through negligence of design standards/philosophies, or through just the standard deviation of manufacturing that may cause errors. These can be compensated for via updates and maintenance, but they can also be exploited by sapient threats.
Natural weaknesses are dangers that occur in the natural environment. These dangers can interfere with signals or even damage the hardware computing / information systems use for operation. While computing systems can be protected from these natural weaknesses, sometimes protection measures fail.

|Evil Twin Access Point||A system that masquerades as a wireless access point.|
|Code Injection||If raw data is not examined for possible attacks when parsed by users on any level of the system (which is resource intense and often inefficient), the code to signify the end of raw data can be given and the system will anticipate executable code to follow. Code can then be injected on the end of the data into the interpreter|
|Buffer Overflow||Similar to code injection, the same principle is instead applied to memory.|
In both military and civilian organizations, the importance of information security is paramount. Raw Data as well as the Information gleaned from said data is a currency unto itself and much therefore be protected just as much, if not more, as any other asset.
In this regard, Information Specialists and their AI / SI Assistants are necessary in order to be both proactive and reactive against any possible threat. They would be responsible for the protection of any and all data in their respective jurisdictions as well as the hardware that stores and processes such data.
A preventative measure used to protect information systems, Access Control revolves around the physical and electronic restriction of information based upon certain criteria. Over all, Access Control has three functions: Authentication, Authorization, and Auditing. Authentication means assessing the identity of each individual claiming to use system resources. Authorizations are the specific permissions an authorized individual can access. Auditing is the collecting of information about an individuals activities while logged onto the system.
For Authentication, a simple password is never enough. At this point, two-factor or multifactor authentication are necessary for a strong authentication set-up (though Mimics and man-in-the-middle attacks may negate such endeavors).
|Methods of Authentication|
|Reusable Passwords||An outdated model of authentication using a series of characters/numbers to identify a user. Easy to crack and easy to obtain. Usage of reusable passwords requires strict policies.|
|One-Time Password Tokens||Small devices that generate one-time usage passwords from either connection to a server or synced seed generation. Works by creating an expected answer with the other machine then has to solve from a sensitive question which is not transmitted. Solves a few issues of reusable passwords.|
|Obfuscation||The act of hiding meaningful information as meaningless information - either as background static noise or as gibberish. Unlike encryption, cannot be solved mathematically and relies on both parties knowing the complete 'language'.|
|Media Tokens||Small devices that plug into systems to authenticate a user6).|
|Proximity Access Tokens||Small devices that transmit authentication data to readers7).|
|Magnetic Strip Cards||Primitive identification cards that store authentication data on a magnetic strip.|
|SMART Cards||Cards with built-in microprocessors and memory, which allow more sophisticated authentication methods.|
|Biometrics||Systems that read biometric data to authenticate users. Some examples range from primitive finger print scans to retinal pattern scans to even genetic scans.|
Part of Authorization is the appropriate permissions individuals have when they finally log onto the system. To assign these permissions, there are two methods of assigning these permissions. Individual Access Control is the procedure in which individuals are assigned these permissions, which is a time consuming operation. Because of this, many users are assigned roles where permissions are then applied to those roles. This is known as role-based access control. This ability to access the system can be further broken down into whether departments or sub-divisions can assign roles or not. In Mandatory Access Control, a central authority is responsible for assigning roles and permissions. Discretionary Access Control is more flexible and allows departments and sub-divisions to assign roles to their members.
In Auditing a System, all access and activities to a system must be recorded and logged in secured servers / sections of the system. This allows IT Security personnel to periodically examine these logs for signs of suspicious activity. With the advent of Artificial / Synthetic Intelligences comes the ability to have these logs monitored constantly and quickly in order to speed up the process of identifying and neutralizing intruders into systems.
While a part of Access Control, Physical Access to terminals and core components of Information / Computing Systems must be strictly monitored and controlled. This means that core components of a system are not centralized and distributed in a manner where damage to one location will not destroy the system as a whole. These facilities must also be secure with access to them restricted to necessary personnel only and all terminals / equipment must be physically secured to their locations.
Securing these areas also means denying unauthorized equipment as well. Recording equipment and storage media should be limited to those authorized by the organization or banned altogether. These facilities need to be monitored as well, which means recording activity both at the entryway and inside the facility as well.
The basic method of communicating confidentially is via a cryptographic system. Communication between two systems begins with three handshaking stages before actual communication can start. Initial Negotiation involves the selection of a cipher suite by both parties. Initial Authentication involves testing the identity of each communication partner, creating a baseline reading. Keying involves sending cipher keys securely for authentication purposes. These handshaking stages are done automatically and leads to the actual communication between the two partners. This requires message-by-message authentication and includes an electronic signature in every message so the systems may identify each other. Digital signatures may also be used to authenticate single messages with keys.
Some primitive methods of ciphers involve public-private key encryption and hashing. Public keys are keys used by individuals to identify themselves and are openly available to everyone. Private keys correspond to public keys but are kept secret from everyone but the communication partners, who use the private key to decrypt messages sent by their public keys. Hashing is applied to binary messages and produces and irreversible cipher-text that cannot be decrypted like encryption.
However, with the advent of quantum computing, quantum encryption has come to be the norm. This is done via quantum key distribution, which can deliver enormously long one-time keys to communication partners as long as the entire message. While not susceptible to normal cryptanalysis and attempts to eavesdrop can be immediately apparent, quantum key cracking by AI/SI assisted cyber warfare specialists may be done. Quantum key cracking is essentially a brute force method of cracking by trying thousands of possible keys at once. This doesn't even count the usage of quantum networking either, since the interception of quantum transmissions requires specific equipment that is precisely tuned. If not tuned properly, the transmitted message could come out garbled and unreadable.
This makes intercepting and decrypting transmissions from quantum computers a time-consuming and frustrating affair for everyone, including the more technologically advanced nations. It means that data theft is often easier via the social engineering methods or even by placing imposters into organizations than by intercepting transmissions.
The following are countermeasures to tools and techniques of hackers.
|Black Holing||Denial-of-Service||Dropping all IP packets from an attacker. Short-term strategy since attackers can change source IP addresses.|
|Validating Handshake||Denial-of-Service||Creates false openings to distracted attackers.|
|Rate Limiting||Denial-of-Service||Reduces certain types of traffic to a reasonable amount and is a proactive measure against DoS attacks.|
|Static Host Tables||ARP Poisoning||Manually sets network important tables rather than allow dynamic updating. Makes IT specialist have to change tables with the organization.|
|Limiting Local Access||ARP Poisoning||Literally limits the access of the local network from foreign hosts.|
|Firewalls||Provable Attack Packets||Examines packets that pass through it for provable attack packets. Those that test positive are denied entry while others are allowed through.|
|Border Firewall||—||A firewall that sits between external networks and an organizations network.|
|Internal Firewall||—||A firewall that filters traffic passing between parts of an internal network.|
|Application Proxy Firewall||—||A firewall that examines application messages for attack packets.|
|Intrusion Detection Systems||—||Tools that examine streams of packets for suspicious activities that can signal possible attacks. Does not automatically drop packets though so it must be monitored.|
|Intrusion Prevention Systems||—||Acts similar to IDSs, but has the ability to automatically stop possible attacks.|
|Anti-Malware Programs||Malware||A set of programs used for identifying, quarantining, and repairing/purging malware from a system. Some examples of these are Anti-virus, Anti-Spyware, and Anti-rootkit.|
|Honey Pot||—||A false target (often emulated) machine or database isolated and monitored from mission critical systems which exists to fool an attacker into thinking they have attacked successfully. The machine has a false or fake version of whatever the attacker is looking for, fooling them into thinking they have succeeded and relies on the attacker not being able to verify their find through hash or functionality.|
Host Hardening is a set of policies and procedures that involves securing any device with an IP address against intrusion. In order to do this, several tasks must be implemented:
Penetration testing is a procedure in which a security consultant or organisation are hired to perform an agreed attack on the system without malicious intent to test for holes or gaps in security using the same methods real attackers would be.
