Abstract
In the context of the digitalization of criminal proceedings, ensuring the professional security of the defense has become an important issue in contemporary legal scholarship. While the transition to electronic criminal procedure has enhanced the efficiency of legal practice, it has also exposed defense attorneys to new professional risks and cybersecurity threats. This study aims to identify legal and organizational mechanisms for ensuring the professional security of lawyers when using the “E-Zan Komegi” information system and engaging in electronic interaction with criminal justice authorities. Particular attention is paid to the protection of attorney-client privilege during pre-trial investigation and court proceedings, the safeguarding of personal data of suspects and defendants, and information security in handling electronic evidence. The article substantiates the need to develop security standards for digital interaction between law enforcement agencies and the legal profession. The findings demonstrate the importance of improving the electronic warrant system in criminal cases, enhancing the security of digital attorney requests, and strengthening lawyers’ cyber literacy and digital competencies. The study proposes the development of unified guidelines for the secure use of digital technologies by lawyers, the introduction of technical measures to protect confidential lawyer-client communications, and stronger oversight of electronic warrant procedures.
