There are three general classifications of systems based upon system security:  High Security, Low Security, and Null Security.
 
There are three general classifications of systems based upon system security:  High Security, Low Security, and Null Security.
  
=== High Security ===
+
===Empire space===
  
High Security systems are those with a security level of 0.5 to 1.0. Players also commonly use the terms High-sec, Highsec, Hi-sec, and Hisec.
+
Empire space is the name given to the regions which the four main NPC factions hold sovereignty (High Security and Low Security). In Empire space, whether high or low security, [[Frigate#Stealth Bombers|stealth bombers]] can't use [[bombs]] and players cannot deploy [[Gate Games#Bubbles|bubbles]].  
  
In these systems, stargates may have a [[CONCORD]], customs, and/or faction navy presence; stargates and stations will have sentry guns; and aggression (i.e. committing a Criminal level offence) will provoke a response from CONCORD and any nearby sentry guns.  Aggression resulting in the destruction of another player's ship and/or pod will result in a loss of security status.  The higher the security level of the system, the more rapidly CONCORD will arrive to engage the offending player.
+
==== High security ====
  
=== Low Security ===
+
High Security systems are those with a security level of 0.5 to 1.0. [[CONCORD]] will react to hostile actions between pilots, with the response time ranging from almost instant in 1.0 space to up to 19 seconds in 0.5 space. Players also commonly use the terms High, High-sec, Highsec, Hi-sec, and Hisec.
  
Low Security systems are those with a security level of 0.1 to 0.4Players also commonly use the terms Low-sec, Lo-sec, Lowsec, and Losec.
+
In these systems, stargates may be patrolled by NPC CONCORD, customs, and/or faction navy ships, and stargates and stations will have sentry guns. Aggression (i.e. committing a [[Crimewatch|Criminal-level offense]]) will provoke a response from CONCORD and any nearby sentry gunsAggression resulting in the destruction of another player's ship and/or pod will result in a loss of security status.
  
In these systems, stargates and stations will have sentry guns (although fewer than in Highsec), and aggression (i.e. committing a Criminal level offence) will provoke a response from any nearby sentry guns.  Aggression resulting in the destruction of another player's ship and/or pod will result in a loss of security status.
+
==== Low security ====
  
=== Null Security ===
+
Low Security systems are those with a security level of 0.1 to 0.4. Players also commonly use the terms Low, Low-sec, Lo-sec, Lowsec, and Losec. 
  
Null Security systems are those with a security level 0f 0.0.  Players also commonly use the terms Null-sec, Nullsec, and 0.0 (pronounced "zero zero", "zero dot zero", or "oh dot oh").
+
In these systems, stargates and stations will have sentry guns (although fewer than in Highsec), but [[CONCORD]] will '''not''' react to hostile actions between [[pilot]]s, although any nearby sentry guns will still open fire on the attacking player(s) and unprovoked attacks will cause losses of security status.
  
These systems are essentially lawless and no NPC organizations will respond to aggression, nor will actions of any kind result in a loss of security status.
+
=== Null security ===
  
== System Security-Limited Game Mechanics ==
+
Null Security systems are those with a security level of -1.0 to 0.0. Players also commonly use the terms Null, Null-sec, Nullsec, and 0.0 (pronounced "zero zero", "zero dot zero", or "oh dot oh"). The name originates from a time when instead of showing negative security status the displayed statuses were rounded to 0.0.
  
Various game mechanics are affected or limited by system security. These include:
+
These systems are essentially lawless and no NPC organizations will respond to aggression, nor will actions of any kind result in a loss of security status. In nullsec the gloves are off: [[Frigate#Stealth Bombers|stealth bombers]] can use bombs and players can deploy [[Gate Games#Bubbles|bubbles]]; players frequently fly under not-blue-shoot-it ('NBSI') rules of engagement.
  
* [[Asteroid]] types found in asteroid belts.  More lucrative asteroids are generally found in lower-security systems.
+
Null security space can further be split to NPC null and claimable null.
* General difficulty of [[rat]] spawns, including belt and gate rats.  More difficult rats are generally found in lower-security systems.
 
* General difficulty of [[Cosmic_Anomalies|cosmic anomalies]] and [[cosmic signatures]].  More difficult sites are generally found in lower-security systems.
 
* Reward level of [[missions]].  Greater rewards for the same mission are given by agents in lower-security systems.
 
* True capital ships (i.e. ships that specifically require the Capital Ships skill) may not enter highsec systems.
 
  
=== Anchoring ===
+
==== NPC null security space====
 +
 
 +
NPC NullSec is null-security space where the sovereignty is claimed by NPC factions, similar to normal 'Empire' space, and therefore cannot be claimed by [[capsuleer]] alliances.
 +
 
 +
Regions classified as NPC NullSec:
 +
* '''Curse''', ''claimed by Angel Cartel''
 +
* '''Great Wildlands''', ''claimed by Thukker Tribe''
 +
* '''Outer Ring''', ''claimed by Outer Ring Excavations''
 +
* '''Stain''', ''claimed by Sansha's Nation''
 +
* '''Syndicate''', ''claimed by Intaki Syndicate''
 +
* '''Venal''', ''claimed by Guristas Pirates''
 +
 
 +
==== Claimable null security space====
 +
{{main|Sovereignty}}
 +
In the rest of nullsec sovereignty is claimed (or contested!) by capsuleer alliances. Any stations in claimable nullsec will be player-owned and will usually only allow their owners' allies to dock.
 +
 
 +
{{expansion past|1=University policy, until March 2014, was that University pilots were not allowed to enter claimable nullsec, unless in a fleet lead by an [[ILN]] Officer, in order to preserve the University's neurality. That changed in March 2014, after a successful 1-month experiment, and [[Azmodeus Valar]] mailed out "[O]ur month long test of increased Sov Null access has been a success. We will be continuing it indefinitely. This means that anyone can lead a fleet into sovereign null security space for PvP purposes. Do not engage in PvE activities in Sov Null space, and do not participate in structure or sovereignty battles."  See [http://forum.eveuniversity.org/viewtopic.php?f=31&t=76988 this forum thread] for more details. This was later updated to allow PvE activities as well, see the '''Rules of Engagement''' page on [[ROE#Claimable_NullSec|claimable nullsec]].}}

== Wormhole Space ==
 +
{{Main|Wormhole Space}}
 +
<!--
 +
{{:Wormhole Space}}
 +
-->
 +
In terms of security mechanics, Wormhole Space ("w-space") is similar to nullsec: [[CONCORD]] does not monitor what happens in wormhole pockets, players can use bombs and bubbles at will and aggression will not impact player security status.
 +
 
 +
W-space also functions differently from known space ("k-space") in that players do not appear in the Local chat channel until they speak in it. This means there could be 1 player or 100 players in a wormhole system and you would not be able to tell the difference just by looking at the local window.
 +
 
 +

A given system's security level is a real number in the range [-1.0, 1.0].  This is known as the system's True Security Level, True-Sec, or Truesec. It is modified to the value displayed in-game by the following range and rounding rules:<ref name="CCP Explorer">[http://www.eveonline.com/ingameboard.asp?a=topic&threadID=1282632&page=1#4 CCP Explorer forum post]</ref>

A given system's security level is actually a real number between -1.0 and 1.0 to 5 decimal places (this is known as the system's True Security Level, True-Sec, or Truesec). It is rounded and displayed as the system's security level according to the following rules.
  
* [-1.0, 0.0] = nullsec

* If the true security is in between 0.0 and 0.05 the security is rounded up to precision.

A system's true security may be desirable to know because nullsec systems may have a truesec range from -1.0 up to 0.0 which continues to affect various game mechanics, such as asteroid belt and rat quality. A system's rounded truesec value is available via the in-game map, and the unrounded value can be found through the [[official datadump]] or any third-party utilities that use the datadump or the data extracted from it.

Many security related mechanics use the true security instead of the rounded security status, however. A lower True-Sec system has better mission pay-outs than a higher True-Sec system, even if the displayed sec status is the same.

The true security is not visible anywhere in game, instead it can be found in the [https://community.eveonline.com/community/fansites/toolkit/ official datadump] or from [https://esi.tech.ccp.is/latest/#/ ESI API].

Revision as of 15:08, 10 July 2020

Various references to High Security, Low Security, Null Security, and Wormhole Space redirect here. For the EVE University Campuses focused on student activities in each of these areas, see Hi Sec Campus, Low-Sec Campus, Null-Sec Campus, or Wormhole Campus, respectively. Other campuses are listed at Campuses.

A star system's Security Level is a rough measure of how hazardous that particular system is. Players also commonly use the terms Sec Level, System Sec, Security Rating, and Sec Rating. It is displayed in-game as a number with a single decimal place in the range -1.0 to 1.0. Security level should not be confused with Security Status, which is an attribute attached to a player character.

The security level of a player's current system is always displayed in the System Information display on the upper left of the screen, both in space and while docked.

Known space

There are three general classifications of systems based upon system security: High Security, Low Security, and Null Security.

Empire space

Empire space is the name given to the regions which the four main NPC factions hold sovereignty (High Security and Low Security). In Empire space, whether high or low security, stealth bombers can't use bombs and players cannot deploy bubbles.

High security

High Security systems are those with a security level of 0.5 to 1.0. CONCORD will react to hostile actions between pilots, with the response time ranging from almost instant in 1.0 space to up to 19 seconds in 0.5 space. Players also commonly use the terms High, High-sec, Highsec, Hi-sec, and Hisec.

In these systems, stargates may be patrolled by NPC CONCORD, customs, and/or faction navy ships, and stargates and stations will have sentry guns. Aggression (i.e. committing a Criminal-level offense) will provoke a response from CONCORD and any nearby sentry guns. Aggression resulting in the destruction of another player's ship and/or pod will result in a loss of security status.

Low security

Low Security systems are those with a security level of 0.1 to 0.4. Players also commonly use the terms Low, Low-sec, Lo-sec, Lowsec, and Losec.

In these systems, stargates and stations will have sentry guns (although fewer than in Highsec), but CONCORD will not react to hostile actions between pilots, although any nearby sentry guns will still open fire on the attacking player(s) and unprovoked attacks will cause losses of security status.

Null security

Null Security systems are those with a security level of -1.0 to 0.0. Players also commonly use the terms Null, Null-sec, Nullsec, and 0.0 (pronounced "zero zero", "zero dot zero", or "oh dot oh"). The name originates from a time when instead of showing negative security status the displayed statuses were rounded to 0.0.

These systems are essentially lawless and no NPC organizations will respond to aggression, nor will actions of any kind result in a loss of security status. In nullsec the gloves are off: stealth bombers can use bombs and players can deploy bubbles; players frequently fly under not-blue-shoot-it ('NBSI') rules of engagement.

Null security space can further be split to NPC null and claimable null.

NPC null security space

NPC NullSec is null-security space where the sovereignty is claimed by NPC factions, similar to normal 'Empire' space, and therefore cannot be claimed by capsuleer alliances.

Regions classified as NPC NullSec:

  • Curse, claimed by Angel Cartel
  • Great Wildlands, claimed by Thukker Tribe
  • Outer Ring, claimed by Outer Ring Excavations
  • Stain, claimed by Sansha's Nation
  • Syndicate, claimed by Intaki Syndicate
  • Venal, claimed by Guristas Pirates

Claimable null security space

Main article: Sovereignty

In the rest of nullsec sovereignty is claimed (or contested!) by capsuleer alliances. Any stations in claimable nullsec will be player-owned and will usually only allow their owners' allies to dock.

A regularly-updated map of player-owned territory is available here.

Regions classified as Claimable NullSec:

Wormhole Space

Main article: Wormhole Space

In terms of security mechanics, Wormhole Space ("w-space") is similar to nullsec: CONCORD does not monitor what happens in wormhole pockets, players can use bombs and bubbles at will and aggression will not impact player security status.

W-space also functions differently from known space ("k-space") in that players do not appear in the Local chat channel until they speak in it. This means there could be 1 player or 100 players in a wormhole system and you would not be able to tell the difference just by looking at the local window.

Game Mechanics affected by System Security

Various game mechanics are affected or limited by system security. These include:

  • Asteroid types found in asteroid belts. More lucrative asteroids are generally found in lower-security systems.
  • General difficulty of rat spawns, including belt and gate rats. More difficult rats are generally found in lower-security systems.
  • General difficulty of cosmic anomalies and cosmic signatures. More difficult sites are generally found in lower-security systems.
  • Reward level of missions. Greater LP rewards for the same mission are given by agents in lower-security systems.
  • Specific types of wormholes will only form in specific classes of space.
  • In 0.5 space and below the moons can be mined with refineries.

High security space

Low security space

  • CONCORD no longer responds, however NPC guns on gates and stations will respond to illegal aggression.
  • Player-Owned Starbases do not require Empire Charters to operate.

Null security space

  • PVP aggression does not change player security status.
  • Items flagged with the Banned in Empire Space attribute can now be used, including launching bombs, anchoring bubbles, and firing doomsdays.
  • Sentry guns do not take any actions towards players who aggress other players.

Wormhole space

  • Local chat does not display all capsuleers currently in the system, only those that have recently spoken in Local.
  • No stargates are present, wormholes are the sole means of travel.
  • As truesec -1.0, w-space has the highest concentrations of planetary resources.
  • Aggression timers do not restrict jumping through wormholes as they do with stargates and docking. However, every individual wormhole has a one-way 5-minute 'Polarization' timer on it, which restricts multiple repeated jumps through it.
  • Cynosural fields cannot create links to other systems; jump drives cannot be used to enter or leave systems in wormhole space.

Anchoring

The security level of a system may limit what may be anchored in that system. [1]

  • 0.9 - 1.0: Containers may NOT be anchored. Starbases and starbase structures may be anchored except for structures requiring anchoring corp to have system sov.
  • 0.5 - 0.8: Containers, starbases and starbase structures may be anchored except for structures requiring anchoring corp to have system sov.
  • 0.0 - 0.4: All containers and starbase structures may be anchored, except structures requiring anchoring corp to have system sov. [2]
  • -1.0 - 0.0: All containers and starbase structures may be anchored, assuming that anchoring corp has system sov. Player-built stations may be constructed in systems where the corp building the station has sov (as of this writing, player-built stations are completely indestructible and are limited to one station per system).

True security

A given system's security level is actually a real number between -1.0 and 1.0 to 5 decimal places (this is known as the system's True Security Level, True-Sec, or Truesec). It is rounded and displayed as the system's security level according to the following rules.

  • If the true security is in between 0.0 and 0.05 the security is rounded up to precision.
  • Otherwise round to precision.

Many security related mechanics use the true security instead of the rounded security status, however. A lower True-Sec system has better mission pay-outs than a higher True-Sec system, even if the displayed sec status is the same.
