By Dilip H. Liyanage –
A Nationally and Internationally Aligned Security Standard
The UN Standard Minimum Rules for the Treatment of Prisoners (the Nelson Mandela Rules) and national prison laws say that correctional facilities must find a careful balance between security, following the law, and treating people who are not free in a fair way. Keeping drugs and unauthorised cell phones out of the facility is an important part of keeping the place safe, protecting staff, the well-being of inmates, and the integrity of the justice system.
In many places, both regionally and globally, institutions that are good at controlling contraband have great leaders, operations based on intelligence, a layered infrastructure, disciplined work practices, and legal, humane procedures. Below, these practices are examined with more explanation and in line with international standards.
1. Leadership-Driven Culture of Discipline, Integrity, and Accountability
Aligned with UNODC Prison Management Framework & ICPA Leadership Standards
Effective security environments are shaped primarily by the quality of leadership. Institutions that maintain superior control over narcotics and mobile phone entry demonstrate:
a. Ethical and Lawful Command Structure
* Senior management makes sure that departmental guidelines, national prison laws, and human rights requirements are strictly followed.
* The leadership establishes a clear security philosophy that emphasises zero tolerance for contraband and is upheld by appropriate and legal measures.
b. Coordinated Multi-Level Command
* Middle-level managers translate strategy into operational performance, ensuring procedures match national rules and maintain recorded accountability.
* Officers at all levels understand their legal duties, including maintaining safe environments under prison acts and regulations.
c. Frontline Professionalism
* Officers practice vigilance, restraint, and ethical conduct—consistent with the Nelson Mandela Rules, which require staff to act professionally and respect human dignity.
* Regular briefing, debriefing, and training reinforce expectations and strengthen institutional culture.
Why this matters:
Leadership determines the moral climate of an institution. Where leaders demonstrate fairness, consistency, discipline, and integrity, contraband networks struggle to survive.
2. Multi-Layered Mechanisms of Control
Consistent with UNODC “Technical Guide on Prison Security and Safety”
A single measure cannot prevent contraband. High-performing institutions use a multi-barrier security model, where each layer compensates for weaknesses in another. This aligns with the legal requirement to maintain order and safety while upholding proportionality and dignity.
a. Perimeter and Physical Security Controls
* Surveillance systems, motion detection, patrols, and secure physical barriers.
* Prevents external throwing, drone-assisted deliveries, and perimeter access attempts.
b. Movement-Related Controls
* Searches and supervision during hospital visits, court transfers, work details, and external movements.
* Ensures that movement opportunities are not exploited for smuggling.
c. Visitor and External Party Oversight
* Screening procedures (scanners, metal detectors, bag checks) aligned with national law.
* Visitor registers, biometrics, and CCTV ensure transparency and protect staff integrity.
d. Staff–Inmate Interface Safeguards
* Clear professional boundaries enforced
* Routine inspections to prevent coercion or collusion
e. Intelligence-Led Operations
* Confidential informant channels
* Analysis of behavioural indicators
* Incident pattern mapping
* Coordinated reporting between departments
This mirrors models used in Singapore Prison Service, UK HM Prison Service, Canadian Correctional Service, and US Federal Bureau of Prisons.
3. Structured, Fair, and Transparent Response to Detections
Aligned with Nelson Mandela Rules (Disciplinary Framework), CPT Standards, National Law
Disciplinary measures must be proportionate, lawful, documented, and reviewable. They must protect institutional order without violating detainee rights.
A. Initial Actions (Procedurally Mandatory)
* Immediate documentation using legally approved formats
* Chain-of-custody maintenance for evidentiary items
* Temporary movement or reallocation to maintain safety and order
* Revision or restriction of visits based on risk (never as punishment)
B. Secondary Measures (Progressive and Fair)
* Scheduled reviews by authorized officers
* Enhanced observation for high-risk individuals
* Transfers between units to disrupt illicit networks
C. Escalated Actions (When Legal Thresholds Are Exceeded)
* Formal referral to police or investigative authorities
* Filing of institutional reports in compliance with national laws
* Ensuring the inmate’s access to due process and, where applicable, legal counsel
These steps ensure both operational integrity and human-rights compliance, reinforcing institutional legitimacy.
4. Technology and Infrastructure Strengthening
Global Benchmark: ICPA “Technology in Corrections”, UNODC Digital Security Guidelines
Modern correctional systems rely heavily on advanced detection technology, which significantly reduces contraband inflow and strengthens lawful enforcement.
a. Body-Scanning Technology – Highest International Priority
* Globally recognized as the most effective tool for detecting concealed contraband
* Reduces invasive search practices, improving rights compliance
* Used in the US, UK, Australia, Singapore, and the EU
b. Communication Control Technologies
* Managed cellphone signal control (preferred internationally over crude jamming)
* Prevents coordination of criminal activity
* Supports legal mandates for safe custody
c. Enhanced Search Technologies
* Ion scanners, metal detectors, handheld imaging systems
* Narcotics-detection K9 units
* Digital monitoring systems for surveillance and pattern analysis
d. Infrastructure Maintenance Standards
* Scheduled calibration
* Documented functionality audits
* Staff competency training
* Compliance with safety and radiation regulations (for scanners)
Technology is effective only when combined with procedural discipline, legal safeguards, and a trained, ethical workforce.
Conclusion
Consistent with UNODC Correctional Reform Principles
Correctional institutions committed to legal compliance and professional standards can significantly reduce narcotics and mobile phone entry by integrating:
* Ethical, disciplined leadership
* Intelligence-led, multi-layered security systems
* Transparent and fair disciplinary frameworks
* Modern technology with documented governance
* Adherence to national laws and international human-rights norms
These practices reflect global best-performing correctional systems and provide a scalable, nationally adaptable modelfor strengthening institutional safety, reducing contraband-related violence, and promoting an orderly, rights-respecting correctional environment.
By adopting these standards, institutions can ensure improved security outcomes without compromising dignity, legality, or professional ethics, demonstrating a strong and modern correctional administration aligned with global expectations.

Dear Dilip,
Thank you for the summary of technology from overseas, where you are domiciled, leading a comfy life amidst fluttering green leaves.
Friend, every Public Servant, in fact, all workers in SL, fear their pay day at the end of the month. Bills galore, debts galore, demands galore; the worker’s worst walk home after pay occurs at the end of each month.
Except for the handful of disco-goers in Colombo, the rest of the population lives well below the poverty line.
A couple of thousand to let a phone into prison and, a step further, turn a blind eye to narcotic smuggling and the few green notes folded in the Driver’s Licence of a traffic offender, aren’t they welcome reliefs?
The poverty situation since Sept 2024 has plunged into immense depths. Ministers are openly saying that it is a shame to be Avesuma.
The next Argalayaya will not be led by the middle class but by the proletariat.
