Security Strategies

Security strategies for the process industries are generally based on the application of four key concepts against each threat deterrence, detection, delay, and response. ... 

Delay—a security strategy to provide various barriers to slow the progress of a perpetrator in penetrating a site to prevent an attack or theft, or... 

Detect—a security strategy to identify a perpetrator attempting to commit a chemical security event or other criminal activity in order to provide real-time observation as well as postincident analysis of the activities and identity of the perpetrator. 

Deter—a security strategy to prevent or discourage the occurrence of a breach of security by means of fear or doubt. Physical security systems, such as warning signs, lights, uniformed guards, cameras, and bars are examples of systems that provide deterrence. 

The security strategy selected has to ensure that cells containing formulas (on purpose, by mistake, or by the auto-save function) of the spreadsheet cannot be overwritten. In today s standard office network environment, in some cases, the network itself is, not validated and does not fulfill the electronic record/electro-nic signature requirement. Therefore, the validated spreadsheets should be stored in a protected drive to which only restricted personnel have access. Furthermore, the server used for storage/handling should be qualified. Figure 18.7 is an example. 

On a short-to-medium term basis the main priorities of Georgia pertaining to the energy security strategies are a) diversification of imported natural gas supply and b) rehabilitation and renovation of the hydropower sector ... 

Who will determine how the security strategy will be implemented Who should implement the security countermeasures ... 

Who will be responsible for updating the security strategy when new information on vulnerabihties and threats will be available ... 

Another way to approach the problem of knowledge diversion is to understand the unique proliferation needs of the various types of groups or states. Those needs are driven in large part by the role that NBC weapons play in the security strategies of these groups and states and how far along they are in the process of developing those weapons.

The National Security Strategy expresses this fear as follows In the Cold War, weapons of mass destruction were considered weapons of last resort whose use risked the destruction of those who used them. Today, our enemies see weapons of mass destruction as weapons of choice (ibid., p. 15). 

Third parties can be extremely helpful in vetting site assessments and implementation plans. Currently, as site assessments have been set up within the Responsible Care Code, local law enforcement and fire chiefs can look at facility plans. They may be very familiar with the emergency response aspects of a site security plan, but they may not always be the best choice when determining other security strategies or assessing investments. 

The results of the study in HA solution suggest a simple but secure strategy to control the reaction by anomalous diffusion occurring in biological systems. The simple polymer solution used here is not only a model for ECM but also one to be extended to other biological space such as cytoplasm and membranes. 

Response—a security strategy to neutralize the adversary or to evacuate, shelter in place, call local authorities, control a release, or take other mitigation actions... 

In addition to mitigating and preventing the potential consequences, security strategies often employ four basic objectives to help minimize the attractiveness, vulnerability, and threat ...

Two-person rule—A security strategy that requires two people to be present in or gain access to a secured area to prevent unobserved access by any individual. 

Chemical facility security is rarely treated separately from general security concerns. At both national and institutional levels, there are no plans for security of chemical facilities and storage sites. Vulnerability assessments are rare, and hidden dangers are poorly understood. In the absence of a specialized security strategy, generic security measures are applied to chemical laboratory facilities. 

This paper works towards this goal. It presents a framework to jointly model and analyze the security and performance attributes of software architectures. The critical aspect that we tackle is to quantify the performance degradation incurred to achieve the security requirements. The basic idea is that the solution of a performance model that embeds security aspects provides values of indices that can be compared to the ones obtained for the same model (i) without security solutions, (ii) with different security mechanisms and (iii) with different implementations of the same mechanism. Such comparisons help software architects to decide if it is feasible to introduce/modify/remove security strategies on the basis of (possibly new) requirements.
