Every participant in this project has the documents they require to share among themselves in the team. In such situation, everybody is in the position to alter and add information to the portal. This contradicts the enterprise information portal; and any user the authority to retrieve and add information to the portal framework (Oracle Application Server Portal, 2005). New developments of control portals include Entrance control which demands the integration of control reader so as to allow users to present their credentials (RS2 Technologies, 2009).
This portal enhances the degree of security of access control system by both offering a means of detecting intruders or physical barriers to bar unauthorized access and producing an alarm. New developments in control portals include the invention of turnstiles. Turnstiles are unique in that they limit passage to one person at ago. Turnstiles have the ability to allow one direction passage and can bar individuals that have not surrendered the right identification or paid the required fee from accessing certain points.
Because of their advanced technology, turnstiles are widely used in office lobbies, toilets public transport stations, stadiums among others Sentry Security System Inc., 2016). Locking devices An Access Control System (ACS) is applicable for any door that one may wish to monitor and regulate access. Exterior and interior doors can be easily observed with contacts, readers, and some locking devices. There are new developments in locking devices that vary from the simple Maglocks to the complex motor locks (Center for Protection of National Infrastructure, 2013).
The new evolution of the lock devices includes the motor, solenoid, solenoid handle and electric locks. The motor lock is more advanced and suitable for the high-security level. These locks use deadbolts and in the case of a power blackout, the lock will remain in the position it was at the time of power interruption. It only takes seconds to withdraw the deadbolt of a motor lock (Sentry Security System Inc., 2016). The second in the rank is the Solenoid handle lock operates in the same way like traditional mechanical latch lock, although it can disable either one or both handles.
Solenoid handle door is more advanced than the solenoid locks. Solenoid locks work in the same manner as an electric strike, except that the mechanism is restricted inside the lock case. The solenoid moves a pin which dislocates or engages the handle movement to the latch. When locked, the handle moves normally, but it remains unconnected to the lock, allowing the handle to move freely without any effect. When unlocked, the lock reacts like a conventional lock causing movements on the handle and finally pulling the latch inside.
Under attack, this type of lock device is also suitable for high-level security because the lock behaves in a similar manner like a conventional lock (British Security Industry Association. 2016). Cards and other tokens Most access control systems require access card readers and control cards. These systems require readable cards so that the cardholders can unlock doors by availing their respective card to the reading device. In simple situations, the card will either open the gate or not. In the advanced system, the card may selectively permit entry through some entrance and not through others.
The card stores information about who can access what and who has what card. The reader at any access controlled door transmits the given details of the card to the controller for validations of the card’s permission (Sentry Security System Inc., 2016). Initially, card readers would use only a magnetic strike; however, currently they use proximity cards which have Radio Frequency Identification (RFID). This technology just requires the card to be held near the reader for it to be validated.
Such cards do not wear out, and they are not easily duplicated. The only demerits with these cards are that they can be stolen, lent or misplaced; hence, giving access to unauthorized access.
