Cryptographic protocols are the cornerstone of security in distributed systems. The formal analysis of their properties is accordingly one of the focus points of the security community, and is usually split among two groups. In the first group, one focuses on trace-based security properties such as confidentiality and authentication, and provides decision procedures for the existence of attacks...

New techniques, tactics, and procedures (TTPs) are now available to strengthen security postures and become more resilient to cyber threats. Most of these technologies are accessible and affordable, and they are showing promising results. This paper exemplifies eight specific advanced techniques, tactics, and procedures to counter cyber threats, including using moving target architectures to co...

Security methodologies are constantly changing and improving hence becoming a challenge for IT organization to keep their posture up-to-date and effective. It may be productive to examine different security postures to create and improve organization’s information security architecture. This paper discusses about defense in depth model and strategy to implement it effectively. Also fructificati...

In this paper we redefine information security by extending its definition in three salient avenues: locale (beyond the boundary of an enterprise to include partner organizations), role (beyond the information custodians’ view to include information consumers’ and managers’ views), and resource (beyond technical dimensions to include managerial dimensions). Based on our definition, we develop a...

Unification algorithms are central components in constraint solving procedures for security protocol analysis. For the analysis of security protocols with XOR a unification algorithm for an equational theory including ACUN is required. While such an algorithm can easily be obtained using general combination methods such methods do not yield practical unification algorithms. In this work, we pre...

Research on the automatic analysis of cryptographic protocols has so far mainly concentrated on reachability properties, such as secrecy and authentication. Only recently it was shown that certain game-theoretic security properties, such as balance for contract-signing protocols, are decidable in a Dolev-Yao style model with a bounded number of sessions but unbounded message size. However, this...

for each country, national security in the most urgent and significant value and need, so each government tries to justify its policies and strategies in order to reach and preserve national security. acquiring national security is, people should share national interests by haying health, land integrity, independence, power, credits and all the values generally. they should be sure of this secu...

This document defines protocols, procedures, and conventions to be employed by peers implementing the Generic Security Service Application Program Interface (GSS-API) when using the Extensible Authentication Protocol mechanism. Through the GS2 family of mechanisms defined in RFC 5801, these protocols also define how Simple Authentication and Security Layer (SASL) applications use the Extensible...
