The paper proposes a method for solving problems of classifying multi-step attacks on wireless sensor networks in the conditions of uncertainty (incompleteness and inconsistency) of the observed signs of attacks. The method aims to eliminate the uncertainty of classification of attacks on networks of this class one the base of the use of neural network approaches to the processing of incomplete and contradictory knowledge on possible attack characteristics. It allows increasing objectivity (accuracy and reliability) of information security monitoring in modern software and hardware systems and Internet of Things networks that actively exploit advantages of wireless sensor networks.

The use of technology is increasing nowadays. On the other hand, most governments and legal offices still do not use technology to implement simple things such as signing a document because they still rely on face-to-face to ensure the authenticity of the signatory. Several challenges may come while signing documents online such as, how to authenticate the signing parties and how to ensure that signing parties will not deny their signatures in future? These challenges are addressed by SecureSign system that attach the signatories' identity with their fingerprints. SecureSign was implemented in C\# and Microsoft SQL Server Management Studio, with integrating fingerprint reader and electronic signature tablet. The SecureSign system achieves the main security goals which are confidentiality, authentication, non-repudiation and integrity. It will have an impact on society and business environments positively as it will reduce fraud and forgery, and help in controlling the process of signing either in contracts or confidential papers. SecureSign have Successfully achieved confidentiality by encrypting data using AES algorithm, authentication by using user fingerprint, nonrepudiation by associating the user ID with his fingerprint, and integrity by embedding QR barcode within the document and hashing its content.
