Security (Onlink)
From Ferrous Moon Research
The systems you will attempt to compromise in Onlink aren't defenseless. This is a list of all the security systems that target machines can employ against you. There are 2 major types: Restrictive Systems, that limit your access on the target system, and Protective Systems, that protect the target system.

Restrictive Systems
These systems are desgined to restrict your access to the target system. You will need to solve/bypass them in order to gain access.
Password Screen
The basic, front line defense of a target system is the password-protected login. Most systems have an account with the username "admin", but Banks are unique in this, in that there are only account numbers available.
Use the Password Breaker to bypass these screens. Sometimes, you can use the Dictionary Hacker too, but it's not as reliable as the Password Breaker. Note that in both cases, the presence of a Bandwidth Monitor can retard your attack.
Elliptic Curve Cypher
Higher security systems often emloy the Elliptic Curve Cypher as a restrictive security measure. The system requires the user to input a large block of data in perfect sync with the system.
You will need the Decypher tool to bypass these screens. However, the Decypher tool is extremely CPU intensive - you will require speeds of at least 200GHz to run the Decypher with any sort of reasonable effect.
Voice Analysis
Some systems - such as banks and mainframes - require users to input a voice pattern, which is then verified. Usually, the only valid pattern belongs to the company's Systems Administrator.
You will need a Voice Analyser - and a valid voice sample - to get past these screens.

Protective Systems
These systems are designed to protect the target system, and - in most cases - will need to be bypassed or disabled in order to carry out your task.
Bandwidth Monitor
The Bandwidth Monitor security programs, or B_Monitor for short (not to be confused with the Monitor security program, discussed later), presumably prevents users from overloading the bandwidth of the protected system. In-game, this manifests itself by preventing Password Breaker from working properly: it will never discover the password for an account as long as B_Monitor is in effect. Disable it with either B_Monitor Disabler (of an appropriate or greater version) or B_Monitor Killer, or bypass the security program with B_Monitor Bypasser (of an appropriate or greater version; requires HUD_ViewConnectionAnalysis first).
Firewall
The Firewall security program prevents users from accessing, altering, or deleting (amongst other things) data, files, and/or programs on a protected system. In-game, the Firewall prevents users from doing anything inside a system until the Firewall is disabled or bypassed. Disable with Firewall Disabler (of an appropriate or greater version) or Firewall Killer, or bypass the security program with Firewall Bypasser (of an appropriate or greater version; requires HUD_ViewConnectionAnalysis first).
Monitor
The Monitor security program does not directly impede a user from accessing anything on a protected system. It does, however, alert the system's administrators and initiates an Active Trace on anyone that attempts to run harmful programming on the system; programs such as Password Breaker or any Disabler/Killer/Bypasser software. Monitor cannot be disabled, except through accessing the "Security" menu once a user has administrator access; it can be bypassed with Monitor Bypasser (of an appropriate or greater version; requires HUD_ViewConnectionAnalysis first).
Proxy
The Proxy security program prevents users from altering data on a system. In-game, this program impedes all actions, including (but not limited to) altering information, accessing data/files/programs, and deleting or otherwise modifying data/files/programs (much in the same way Firewall behaves in-game). Disable with Proxy Disabler (of an appropriate or greater version) or Proxy Killer, or bypass the security program with Proxy Bypasser (of an appropriate or greater version; requires HUD_ViewConnectionAnalysis first).
Sentry
The Sentry security program fools users into believing that modifications to the protected system have been performed, when in reality, they have not. (E.g., deleting a file does not actually delete the file while Sentry is running). Disable with Sentry Disabler (of an appropriate or greater version) or Sentry Killer, or bypass the security program with Sentry Bypasser (of an appropriate or greater version; requires HUD_ViewConnectionAnalysis first).
New Systems: 0.1.2
As of version 0.1.2 of Onlink, these systems have been added.
Active Server Encryption
The ASE system actively encrypts data on the server, for example the passwords in the "records" section of a server. The data cannot be read unless the encrypter is bypassed or disabled.
Default Gateway
The Gateway system is similar to the EBS system in that it actively backs up the files from the mainframe, however the gateway system also monitors the connection for outside attacks that would be requesting the mainframe to preform various tasks. If it detects suspicious activity, it will give the instruction to the mainframe to stop responding to the client. The obvious security flaw in this is that the gateway is not required to be running for the mainframe to work, so an attack on the gateway would leave the mainframe exposed.
EBS
The Emmigrated Backup Service system actively backs up files on a mainframe server, but does not mirror the mainframe's file server exactly (it does not delete files if non-existent)
