A diagram indicating a security alert being enacted

A security alert was a type of alert signal aboard starships and space stations, primarily for internal security purposes. It was similar to an intruder alert, and could be initiated explicitly by personnel or triggered by predefined parameters.

In the 23rd century, a security alert aboard Federation starships was part of the general quarters alert, and had at least three levels. (TOS: "The Man Trap", "Dagger of the Mind") By 2285, security alerts of Federation starship systems such as the Constitution-class were separated from the general quarters alert. (Star Trek III: The Search for Spock)

In the 24th century aboard Galaxy-class and Intrepid-class starships, security alerts had at least five levels of application (also referred to as conditions), each one for different types of situations. On certain space stations, security alerts were distinguished by color. A security alert could be activated with no stated degree.

Levels/Conditions

Level/Condition 10

Aboard the USS Voyager, Captain Kathryn Janeway instituted a level 10 security alert after more former Maquis members now part of her crew were subdued by an unknown assailant. The action also confined non-essential personnel to quarters, and the posting of security teams on all decks. (VOY: "Repression")

Apparently, such a security alert level also included the arming of on-duty personnel with hand phasers at all times as evidenced during the episode. Given the severity of the actions during this alert, it may be the highest level of alert, at least aboard Voyager in 2377, and may have been related to a full alert Janeway called for in 2366.

Level/Condition 4

Aboard the Federation starship USS Enterprise-D, Captain Jean-Luc Picard ordered a level 4 security alert in 2369 after it became apparent that crewmembers were mysteriously disappearing from the vessel. (TNG: "Schisms")

Picard also specifically asked for shields to be raised while placing the security alert, differentiating the alert from a yellow alert.
As well, a level 4 security alert may include more intensive internal scans, since crewmember departures from the starship were not actively reported by the computer until the alert was instituted.

Level/Condition 3

Picard asked Worf to maintain a level 3 security alert after Lieutenant Reginald Barclay reported seeing alien lifeforms while in an extended transporter beam. (TNG: "Realm of Fear")

Picard once again instituted a condition 3 security alert and told the computer to shut down all transporter systems and shuttlebays as Wesley Crusher eluded the crew while they were under the influence of the Ktarian game. (TNG: "The Game")

Picard's secondary order implies that a condition 3 security alert did not include taking the personnel movement systems offline.

Tuvok called a level three security alert aboard Voyager and told all hands to report to duty stations in an attempt to apprehend the mutating Tom Paris. (VOY: "Threshold")

Level/Condition 2

In an alternate timeline created by Q, Picard ordered a level 2 security alert in 2364 after he continued to experience shifting through time. (TNG: "All Good Things...")

Level/Condition 1

Geordi La Forge, seemingly filling in for Worf as security chief, suggested the Enterprise should go to level one security alert while trying to apprehend the devolving Klingon. (TNG: "Genesis")

La Forge already called a level two security alert aboard the vessel before making his recommendation, so this would imply that level one was of greater intensity than the other levels. A full alert might have been the same as a level one alert.

Colors

Yellow

Benjamin Sisko told Kira Nerys to go to security alert yellow when the Norkova started docking. (DS9: "The Passenger")

Full alert

Commander William T. Riker called for a full security alert when criminals inhabiting three of the Enterprise crew's bodies attempted to gain control of the ship. (TNG: "Power Play")

Since Riker explicitly told the computer to transfer command controls to engineering, this type of security alert most likely did not include such action.

Sisko put the entire station at full security alert, and also ordered for all turbolifts secured and to seal off some airlocks. (DS9: "Dax")

Again, disabling personnel transport systems may not be part this type of security alert without specifically requesting it.

Captain Janeway told Chakotay to put Voyager into full security alert in response to the newly realized threat from the Vaadwaur. (VOY: "Dragon's Teeth")

General alerts

Picard called for a security alert to all decks when Ira Graves, who took over the body of Data, attempted to take over the Enterprise. (TNG: "The Schizoid Man")

Worf told the bridge to institute a security alert when he found Singh dead in engineering. (TNG: "Lonely Among Us")

Chief Miles O'Brien was interrupted while attempting to call a security alert by an alien intruder in Transporter Room Three. Worf expanded the alert to all decks after the intruder left the transporter room. (TNG: "The Bonding")

Picard tells Worf to be on security alert when he realized the potential danger of Clara Sutter's imaginary friend. (TNG: "Imaginary Friend")

Data called for a security alert as a mercenary ship fled from the Enterprise. (TNG: "Gambit, Part II")

Riker called a security alert to all decks when alien intruders were expected to transport aboard the Enterprise. (TNG: "Force of Nature")

Since the ship automatically went into red alert after the security alert was called, there may be some connection between the two alert signals.

Altovar triggered a security alert when he broke into the infirmary of Deep Space 9. (DS9: "Distant Voices")

While Tieran had control over Kes' body, Janeway called a security alert as Tieran tried to escape from Voyager. (VOY: "Warlord")

Ensign "Gentry" tried to call a security alert to "Headquarters". (VOY: "In the Flesh")
