Two major options exist for managing security in a seaport.
The first option for managing security in a seaport is that of using state security organs. This is the approach that is used in most places, given the importance of seaports as strategic national installations.
The second option for managing security in a seaport is that of using private security companies. There are some private security companies that are so good that their personnel end up being more effective than state security agents. Here, we are looking at the so-called security contractors, and we know just how well they can perform. Awake to these facts, there are some countries that have opted to have their port security handled by such private security companies, perhaps under public private partnerships, and the whole thing seems to work quite well.
Regardless of the option used, technology can be employed to enhance security further. Of course, seaport security can’t be maintained using technology alone. Seaport security is not like, say, www.gmail.com security, which, to the developers, was just a matter of getting Gmail programming right (on the underlying Gmail.com source code). The nature of seaport security is such that it has to be physical security, hence the need for human intervention.
