With cyber-attacks increasing in number, there is a critical foresight in the sphere of healthcare with Dr. ES Chakravarthy, the former Vice President at TCS Bangalore and Global RMG Head in TCS, designing his predictions about the trends of cybersecurity in this sector in 2026. As decades-long TCS leadership ES Chakravarthy programs are at the forefront of resource management and technology-related adoption, he focuses on active safeguards as the number of ransomware and AI-powered attacks rises.
Evolving Threat Landscape
The next generation of AI-powered attacks comes up. Doctor faked voices might issue a fraudulent transfer, and polymorphic malware may defeat conventional antivirus. Dr. Chakravarthy TCS plans emphasize the use of predictive analytics to identify abnormalities in the flow of patient data within a short time.
Zero Trust Architecture Essential
The guidance of the Dr. ES Chakravarthy Vice President emphasizes zero trust models instead of perimeter defenses. Hospitals should not ignore any access requests irrespective of the location. Multi-factor authentication in EHR, PACS and billing systems becomes a requirement. Micro-segmentation separates the networks of critical wards, which include breaches.
Legacy systems pose risks. A large number of Indian hospitals use windows xp ventilators. Dr. ES. TCS recommendations of Chakravarthy are virtualization wrappers and endpoint detection agents. Quarterly vulnerability scans are required to prevent attacks such as the Log4j variants.
AI and Quantum-Resistant Defenses
By 2026, generative AI is going to reinvent defense. The profile of ES Chakravarthy global head highlights the use of AI to conduct threat hunting on terabytes of logs and in real-time. Behavioral analytics raises insider threats: nurses who have accessed unauthorized celebrity records.
Quantum computing looms. Post-quantum cryptography is future-proofed against harvest-now-decrypt-later type attacks on encrypted histories of patients. The TCS VP Chakravarthy insights propose mixed algorithms such as lattice-based encryption in the transmission of MRI data.
Risks in the supply chain compound. Radiology providers that are vendors add backdoors. Dr. ES Chakravarthy TCS news discloses the stringent vetting systems that examine the compliance of vendor SOC2 of integration prior to integration.
Regulatory Compliance and Training
The enforcement of the DPDP Act requires reduction of data. Hospitals are required to pseudonymize records with only identifiable data being stored to support active treatment. The most recent publications by ES Chakravarthy highlight tabletop exercises of ransomware locking ICUs that have been simulated on an annual basis.
Employee training is changed to phishing simulation in the form of a game. Dr. Chakravarthy TCS is focused on C-suite responsibility- accountability-CEOs liable to pay a fine as required by HIPAA like mandates. CERT Teams Partnerships with CERT-In strengthen native CERT teams.
Future-Proof Implementation Roadmap
TCS approaches Dr. ES Chakravarthy, global RMG leader, has a phased implementation approach: analyze the current posture through penetration tests, implement SIEM tools, and then automate incident response. The budget distribution is biased towards prevention- use 10% IT expenditure on security.
The adoption of such measures by Indian hospitals makes them resilient. Dr. ES Chakravarthy, who is the strategic advisor, cautions against inaction which would cost lives in 48-hour outages. Enlightened CIOs inculcate cybersecurity within the digital transformation, and protect patients with alert innovation.
